Captain America Comics Published: March 1941 by Marvel Comics. Writer: Jack Kirby Illustrator: Jack Kirby This is the first appearance of the iconic Captain America and in it he is shown punching Hitler.
The original Spider-man design by Jack Kirby. You can see his artistic style all over this. Still I'm glad Steve Ditko's design replaced this one as the design says "generic space man with a ray gun" to me.
