Here’s a 1967 Jack Kirby drawing of Spider-Man. Erik Larson shared this on the Kirby Fan Club Facebook page and had some interesting quotes about Kirby’s Spider-Man.
“Kirby always gets Spider-Man’s costume wrong–sometimes gloriously so!”
“The Spider-Man on Kirby’s Amazing Fantasy cover was no doubt fixed by Ditko. There’s a reason Ditko always inked Kirby’s Spider-Man stuff early on and Romita did later on.”
