Hans Krüsi was a self-taught artist who, having completed eight years of school, picked up odd jobs while creating his artworks on the side. Many of his subjects explored his immediate experiences or memories of agrarian labor, as well as his ideas about the relationship between humans and nature. He executed a number of works on paper napkins, and sometimes used the forms and shapes of the napkin to inform the composition. In the 1970s, Krüsi was working as a flower vendor and began to offer his postcard-sized works alongside bouquets at flea markets, on the train, and at his street stall. He began to create monumental-sized installations and sculptural pieces in the mid-1970s, using found objects and multiple mediums.
