Bob Larkin began his career as an illustrator in 1969 and his many credits include titles such as Crazy Magazine, Deadly Hands of Kung-Fu, Marvel Preview, Marvel Super Special, Planet of the Apes, Savage Sword of Conan, and The Tomb of Dracula. Larkin painted covers for many of the Marvel Fireside Books paperback collections, lending them a simple, movie-poster feel. He did the same thing for the cover to the second major intercompany crossover, Superman and Spider-Man. In addition, Marvel occasionally tapped Larkin to paint covers for premiere issues of such comic book titles as Dazzler (March 1981) and The Saga of Crystar (May 1983). A rare example of Larkin providing interior art is the three–page story “For the Next 60 Seconds” in Epic Illustrated #1 (Spring 1980).
Besides his work for Marvel, Larkin has painted covers for Vampirella and The Rook (Warren Publishing), The Amazing Adventures of Holo-Man (Peter Pan Records), Lorelei: Building the Perfect Beast (StarWarp Concepts), and many others.
