Purchased in 1973 for funds from the Purchasing Fund.

The visual artist Per Kleiva (1933-2017) is particularly known for his socially engaged work production, and especially for his graphic production, such as American Butterflies and Pages from Imperialism's Diary.

His series of silkscreens Three Leaves from Imperialism's Diary (1971) is considered icons/iconic in Norwegian art history. Kleiva received the prestigious first prize at the Graphic Biennale in Krakow for the work in 1972. The series which consists of three silkscreen prints is a protest against the Vietnam War. It consists of three photo montages, where the same image of a beautiful landscape with trees and flowers is put together with simple, threatening war symbols such as marching soldier legs, military helicopters and a bomb cloud. The contrast between the peaceful flower meadow in pale green and blue against the black military boots and the row of helicopters is simple, direct and effective.
