Passage:Upon completion of his degree studies at Brera in early 1939, he was drafted by the Italian military for service in World War II. He was deployed to Slovenia, and later to Sicily and Albania, and when his tours of duty were complete, he would participate in art exhibitions. He continued to paint during his service, even when on the front lines, committing to canvas images of "dramatic testimonials" considered prohibited, such as Albanian villages razed by Italian troops.
