Hak always liked to draw; as a kid he copied the comics. In the sixties as part of the underground comics movement, he created comic pages that appeared in Yellow Dog (The Captain) and publications by Print Mint. He contributed cartoons and drawings for the cover of Liberation Magazine and WBAI program guides. His drawings were also published in The Realist, in a New York anarchist publication called Good Soup and as illustrations for works published by Jargon Society and some Small Press poetry reviews.
