Firsts in comic books

The first skin tight costume and mask was The Phantom, February 1937 (comic strips).

The first masked crime fighter--and I guess that means urban crime and not jungle crime-- was The Crimson Avenger, Detective Comics #20, October 1938.

The first superhero was, of course, Superman, June 1938.

The first comic book was Funnies on Parade, 1933.

The first comic book with new material was in February 1935.

And did you know that the first actor to actually dress as Superman was Ray Middleton at the 1939 World's Fair?
