Art credits from David Saunders, Clarence Doore's biographer and foremost authority on his work. There is some confusion on the Norman Saunders website, but this is from a new list made by David Saunders, with credits to all the painted covers of G.I. Joe. April 2011.
Suchorsky is credited to G.I. Joe in 1950-55 by Jerry Bails' Who's Who, and this work is identical to his "Sea Witch" stories in "Pirate Comics", also credited by Bails. He can be noticed by his detailed inking, rounded ears and many lines in faces.
Dan DeCarlo is credited to both pencils and ink on "The Yardbirds" in Jerry Bails' Who's Who, but Rudy Lapick is also credited as his personal inker, and the inking is not to be distinguished from other signed DeCarlo/Lapick stories in G.I. Joe.
Suchorsky is credited to G.I. Joe in Jerry Bails' Who's Who for 1950-55.
Mort Drucker is credited to G.I. Joe for the 50's by Jerry Bails' Who's Who, and this is the only one that has to be by him. The hands and muscles of the arm on page one, and the face of the colonel on the last page looks very much like his work. Jerry Bails credit to the 50's must just mean at some time in the 50's, not necessarily all through the 50's, as he is not found in any other story than this one.
