He also made decorations at St. Olaf College in Northfield, Minnesota and altarpieces for Hornindal Church at Hornindal in Sogn og Fjordane County and Sandefjord Church at Sandefjord in Vestfold county.

Among his works are the painting Jørgen Tjønnstaul in the National Gallery of Norway, a head sculpture of Fridtjof Nansen, and Yggdrasilfrisen in Oslo City Hall. He illustrated the 1939 edition of Nordahl Rolfsen's readers, and editions of Norwegian fairytales.^[2][3]
