From World's Finest Comics #29 (July-August 1947)
Pretty sweet toy.
Wowzers! Those post-Congress and parent group comic book covers were incredibly lame. The lame factor was especially high on those of World's Finest with Superman, Batman and Robin getting all chummy and acting like tourists instead of fighting crime and dropping evil-doers from the top of buildings. Often though, the sanitized and cheery covers were there merely to fake out Mom and Dad about the interiors so they wouldn't see Batman letting some villain die in an acid shower death-trap of his own design originally intended to scour Robin of his flesh.
You know the ones...

"Right, Batman! Let's go for ice cream."
"Ice cream is not good for young, healthy boys, Robin. Instead, let's have some 100% American steaks served with vegetables from our Victory Garden."
