This historical depiction of the coat of arms of Tennessee was illustrated by the American engraver Henry Mitchell in State Arms of the Union, published in 1876 by Louis Prang. The coat of arms includes the Roman numeral "XVI", referring to Tennessee being the 16th state to join the Union. The plough, wheat sheaf, and cotton plant in the top half of the shield illustrate the importance of agriculture to the state's economy, while the flat-bottomed riverboat in the bottom half represents the importance of commerce. This design also appears on the Tennessee state seal.

Wheat Fields is a series of dozens of paintings by the Dutch Post-Impressionist artist Vincent van Gogh borne out of his religious studies and sermons, connection to nature, appreciation of manual laborers and desire to provide a means of offering comfort to others. This 1888 work, titled Corn Harvest in Provence, is one of many oil-on-canvas paintings he created that included them. This harvest scene was painted just outside Arles, and exemplifies Van Gogh's use of colour in full brilliance to depict the "burning brightness of the heat wave". The painting is in the collection of the Israel Museum in Jerusalem.

Don César de Bazan is an opéra comique in four acts by Jules Massenet to a French libretto by Adolphe d'Ennery, Dumanoir and Jules Chantepie, based on a play by d'Ennery and Dumanoir first performed in 1844. This in turn drew on the popular character of Don César de Bazan from the 1838 drama Ruy Blas by Victor Hugo, despite having little connection with the plot of Hugo's drama. This poster, engraved by Célestin Nanteuil, advertised the opera's premiere, which took place at the Opéra-Comique in Paris on 30 November 1872.

Portrait of Wally is a 1912 oil-on-canvas painting by the Austrian artist Egon Schiele, depicting the young model Walburga Neuzil. Although little is known about the subject, she might have been one of his mistresses, and died tragically at a very young age. The painting had been owned by Lea Bondi, a Jewish art dealer who was fleeing the German annexation of Austria and had to sell it in 1939. The work was restituted to the owners only in 2010, it now forms part of the collection of the Leopold Museum in Vienna.

The sapphire-throated hummingbird (Chrysuronia coeruleogularis) is a shiny, metallic-green hummingbird found in Panama, Colombia, and Costa Rica. During flight, hummingbirds have one of the highest metabolic rates among small birds and therefore need to eat more than their own weight of nectar each day to avoid starvation; insects and spiders are also consumed for added protein. Males are polygamous, and after mating play no part in nest-building or rearing the young. This male sapphire-throated hummingbird was photographed in the gardens of Biomuseo, a natural-history museum in Panama City designed by Frank Gehry.

The Bank War was a political struggle that developed over the issue of rechartering the Second Bank of the United States during the presidency of Andrew Jackson (1829–1837). The affair resulted in the shutdown of the Second Bank and its replacement by state banks. Louis McLane, then Secretary of the Treasury, was a prominent figure during the Bank War. This portrait is a line engraving of McLane, produced around 1902 by the Department of the Treasury's Bureau of Engraving and Printing (BEP) as part of a BEP presentation album of the first 42 secretaries of the treasury.

The leopard (Panthera pardus) is one of five extant species in the genus Panthera, a member of the cat family, Felidae. This photograph shows a leopard devouring an impala in Kruger National Park, South Africa. Compared to other wild cats, the leopard has a relatively large skull with powerful jaws, a long body and short legs. It can climb trees very skilfully, often rests on tree branches and can descend to the ground head first. An adult leopard is strong enough to drag a carcass heavier than itself up into a tree, where the prey may be eaten straight away or cached to be consumed later.

The panther chameleon (Furcifer pardalis) is a species of lizard found in tropical forests in the eastern and northern parts of Madagascar. Like all chameleons, the species exhibits a specialized arrangement of toes in which the digits are fused into a group of two and a group of three. On the forelimbs, there are two toes on the outer side of each foot and three on the inside, with the arrangement reversed on the hind legs. Their specialized feet allow them a tight grip on narrow branches, and their sharp claws give them traction when climbing on bark. This male panther chameleon was photographed on the island of Nosy Be, off the northwestern coast of Madagascar.

Ignace-Gaston Pardies (1636–1673) was a French Catholic priest and scientist. His celestial atlas, entitled Globi coelestis in tabulas planas redacti descriptio, comprised six charts of the night sky and was first published in 1674. The atlas uses a gnomonic projection so that the plates make up a cube of the celestial sphere. The constellation figures are drawn from Uranometria, but were carefully reworked and adapted to a broader view of the sky. This is the second plate from a 1693 edition of Pardies's atlas, featuring constellations including Pegasus and Andromeda, visible in the northern sky.

Bryce Canyon National Park is an American national park located in southwestern Utah. The major feature of the park is Bryce Canyon, which despite its name, is not a canyon, but a collection of giant natural amphitheaters along the eastern side of the Paunsaugunt Plateau. This panoramic view, as seen from Inspiration Point, shows the colorful Claron Formation, from which the park's delicate hoodoos are carved; the sediments were laid down in a system of streams and lakes that existed from 63 to about 40 million years ago (from the Paleocene to the Eocene epochs). The brown, pink and red colors are from hematite, the yellows from limonite, and the purples from pyrolusite.

The village weaver (Ploceus cucullatus) is a species of bird in the family Ploceidae, found in much of sub-Saharan Africa. This often abundant species occurs in a wide range of open or semi-open habitats, and frequently forms large, noisy colonies in towns, villages and hotel grounds. This male, of the subspecies P. c. bohndorffi, was photographed building a nest in Queen Elizabeth National Park, Uganda. Male birds make elaborate nests, each incorporating about 300 strips of palm or grass leaves that they have torn off the plant and transported individually. These are woven together to form roofed, dangling structures with the entrance at the bottom. The only involvement of the female is in the creation of the lining of the egg-laying cup.

Emma Smith DeVoe (August 22, 1848 – September 3, 1927) was a leading advocate for women's suffrage in the United States in the early 20th century. She was inspired as a child by hearing a speech by Susan B. Anthony, and became an excellent public speaker over time, being mentored by Anthony herself. After campaigning in South Dakota and successfully obtaining the vote for women in Idaho, the National American Woman Suffrage Association sent her to Kentucky, and she eventually made speeches and organized new suffrage groups in 28 states and territories. Moving to Washington, she was made president of the Washington Equal Suffrage Association; in 1910, the state became the fifth in the country to grant women suffrage.

Argiope trifasciata, the banded garden or banded orb-weaving spider, is a species of arachnid in the family Araneidae. It is native to North and South America but has spread to other parts of the world. This ventral view of a female A. trifasciata shows her in the centre of her web, which can reach a diameter of 60 cm (24 in). The function of the zig-zag web decorations is unclear, but they may serve to make the spider appear larger or to act as a warning sign.

The Fiancée of Belus is a large narrative painting by the French artist Henri-Paul Motte based on a fanciful Babylonian ritual associated with the deity Belus (Bel). According to that ritual, the deity was offered a girl who sat on the lap of Bel's statue overnight, to be replaced the following day by another. All the girls were said to have been winners of daily beauty contests. For the interior of the Babylonian temple, Motte copied the Greek temple in Olympia, while the sculpture is inspired by the Assyrian deity Lamassu. The painting is in the collection of the Musée d'Orsay.

The Guilty Mother is the third play of the Figaro trilogy by Pierre Beaumarchais, following The Barber of Seville and The Marriage of Figaro. Like its predecessors, it has been turned into operatic form, but unlike them, has failed to enter the general opera repertoire. This 1876 illustration by Émile Bayard shows one of the main characters, the Irishman Bégearss, a major in the Spanish military, and a great schemer and stirrer-up of trouble.

The Campbell albatross (Thalassarche impavida) is a medium-sized mollymawk in the albatross family, Diomedeidae. It breeds only on Campbell Island / Motu Ihupuku and the associated islet of Jeanette Marie, in an uninhabited subantarctic island group of New Zealand located in the South Pacific. Because of its restricted breeding range, the bird is considered to be a vulnerable species by the International Union for Conservation of Nature. The greatest threat it faces is from the fishing industry. This Campbell albatross in flight was photographed off the south-eastern coast of Tasmania, Australia.

Albury railway station is a heritage-listed railway station at Railway Place in Albury, New South Wales, adjacent to the border with the state of Victoria, in Australia. The buildings were erected in 1880 and 1881, at a time when increasing wool trade from the Riverina region was driving expansion of the railway network. The station was the terminus for the Main Southern Railway until 1962. The yard was designed to facilitate the interchange of goods and passenger traffic arriving on tracks of different gauges and remains as an operational railway yard and passenger station. To accommodate the break of gauge, a very long railway platform was built, the covered platform being one of the longest in Australia.
