In 1953, Zuber demobilized in Kingston, Ontario where he completed studies in photography and Fine Art. He lived in Montreal from 1955 to 1972 and worked as a commercial photographer and painter. In 1972, he moved to the Kingston area to work on full-time painting.
In 1975, Zuber began painting what would become the Korean War Memorial Paintings. From memory and sketch diaries he kept in the field, he recreated his Korean experiences. He exhibited the works in Kingston in 1989, and the Canadian War Museum took an interest.
Through a benefactor, the Canadian War Museum purchased the original paintings. The Canada Council has declared the Korean War Paintings heritage works. Canada had no official war artist in Korea, so Zuber’s work form a very important record of the Canadians in Korea.
