WILD MAN WITH A PEN: Isaac Welsh has been drawing up a storm almost since before he could crawl, perfecting — and insisting on — a style all his own. Stubbornly self-taught — notwithstanding obvious inspiration from the likes of Ed “Big Daddy” Roth, EC Comics, Dragon Ball Z, Calvin and Hobbes, and, of course, the perpetual cat-and-mouse game between Batman and the Joker — Welsh will soon be venturing forth to art school in San Francisco to expand his chops, expand his horizons, and further challenge himself creatively.
