Rock is a pencil jockey by trade. He's done work for AC Comics, Main Enterprises, and Moonstone, among others. Some of the strips he's created include Dinosaur Girl (AC Comics, creator, writer, pencils), Crissy Carrots (Main, creator, writer, pencils), and Betsy the Bookwriter (Main, co-creator, writer, pencils). His specialty is cheesecake cartooning (what they call "good girl art" these days).
Bettie Page is probably the undisputed cheesecake queen. A very prolific magazine, figure and photo club model during the 1950s, seemingly millions of photos were taken of her in just about every situation imaginable.
