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.
Allen Anderson had only three covers in the first volume of G.I. Joe.
Novick is credited to G.I. Joe on both pencils and ink in 1950-54 by Jerry Bails' Who's Who, but the inking here can be by Giacoia, who is credited to ink on G.I. Joe in 1952 by Jerry Bails' Who's Who. The close up faces looking behind is Novick.
Henry Sharp is credited to G.I. Joe by Jerry Bails' Who's Who, and the artwork is identical to credited stories in "Amazing Adventures" #4 and "Nightmare" #10. Very large mouth when shouting, scribbly inking, broad grinning faces with big ears, and much funny cartoon style movement.
Signed HR; possible full name from Bails and Ware
Dan DeCarlo is credited to both pencils and ink on Wendy the WAF 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.
Brown is credited to (pen/-) and Gantz to (lay/ink) by Jerry Bails' Who's Who.
Novick is credited to both pencils and ink on G.I. Joe, and Giacoia only on ink in 1952, and Novick had more thin inklines than here. Jerry Bails' Who's Who may have missed Giacoia work in 1953... Uncertain credit.
