wait, worldcup. i think he battle spies in the serial. so, that would more likely place it in the war years - more likely 40's.
still lame ass. no way someone can dress up like a bat and not look like a lame ass.
i guess that's why he's best as a cartoon.
actually, i hate to be a prick, but it would've been a bit later than the 30s, right? action comics #1 came out in 1939, and superman predated batman. i thought batman came along in '42 or '43.
as usual, i could be wrong.
