Col. Pud’s Single Shot is great from cover to cover. It features anthro art with a style and a sense of humor you rarely see in today’s comics, let alone a furry fanzine from 1981.
But it also holds a mystery, it seems it was published for something called Denvercon. Which after repeated searches I found nothing on, and have asked the Greymuzzle community at large to see what they know. But for now it’s a mystery.
