The bulk of the collection is comprised of images of paintings by Vladimir Kozak and his artifacts relating to Brazilian tribes, photographed by James A. Jensen at Kozak's home in Curitaba, Brazil, in September 1965. It also includes a watercolor image of body decoration at a ceremony held by the upper Xingu River tibes of Central Brazil. Additionally, there is one lithograph poster of a J. A. Jensen painting of Chief Joseph, dated 1974.
James A. Jensen (1918-1998) was a paleontologist and Director of the Earth Sciences Museum at Brigham Young University (BYU). While at BYU, he conducted fieldwork in both North and South America, at which point he may have met Vladimir Kozak. He created pastel and acrylic artwork, particularly of flowers, landscapes, and Native Americans.
Artist Vladimir Kozak was trained in Czechoslovakia in mechanical engineering, sculpture, and painting. In 1923, he immigrated to Brazil. As Kozak's interest in the Indigenous tribes of Brazil grew, he increasingly focused on painting and sculpting, particularly during the 1940s and 1950s. He also became a still photographer, film maker, and collector of Indigenous artifacts.
