There are no art credits in the printed comic. Art is credited to: "almost the whole blamed Bullpen!". Jerry Grandenetti pencil credit added by Mark Evanier (via the GCD Errors list, August 2009), who credits him with about half of the story. Everett appears to have penciled and inked part of the first two pages, with Grandenetti pencilling the rest, although the Hulk and Rick Jones' face was apparently drawn by Everett throughout the story to maintain consistency. Primary inker is likely Mike Esposito, with possible assistance from Sol Brodsky and John Tartaglione. Gene Colan and Dick Ayers art on page 5, panels 1 and 2, are taken from the Sub-Mariner story. Inks formerly credited to Bill Everett, Dick Ayers, Paul Reinman and John Romita, Sr. (Current credits per Nick Caputo.)
