"The Case of the Bomb Defense Formula"
If you thought Batman's appearance in All-Star Comics #7 was a cheat, this issue is a downright con. At least in issue 7, Batman does make an appearance, albeit at the very end of the story; but here, it's a different story. The cover of the issue sports the honorary members of the Justice Society with a story set five hundred years in the future. And Batman is mentioned twice and only seen once - sort of.

The story opens as the JSA rescues a group of scientists involved in the war effort. One of them has a formula that can act as a perfect air defense, but he cannot remember it. The League decides to travel 500 years into the future thanks to a device one of the scientists has developed. They leave honorary members Green Lantern and Flash behind to guard the scientists. Batman and Superman get their first mention as they are too busy to help.
Really?
