Batman 18, 1943

It should be pretty obvious why this cover is so cool. There's Batman & Robin, who everyone knows and loves. Hitler, Mussolini and Hirohito get K.O.'d by a giant 4th of July firecracker. Plus we are commanded to "buy war bonds and stamps!" This is just a cool, fun comic! Art by Jerry Robinson who drew a lot of old Batman comics.

P.S. I no longer own this comic, it was sold in June 2005 for $280.
