Note the date -- 1972. This is just about the earliest cover I ever did for a fanzine. (There might be one or two earlier, but not by much.) It was originally meant for the local Toronto clubzine, but the editor LOST the artwork. It was for all intensive purposes in the Twilight Zone for I guess four years, before it was finally found again.
I submitted it to Mike Glyer right away, who used it for his genzine Prehensile. Later Mike began another genzine called Scientifriction, and later still settled into old age gracefully by starting File 770.
