This issue's tale of the World's Finest team has been reprinted several times already but it's a fun one so here it is again. Sci-fi veteran Edmond Hamilton writes this time travel story with Dick Sprang and Stan Kye on the art.
Oddly enough, the most important page in the issue is the ad below for the first issue of SHOWCASE. It wasn't much really and neither were the next couple of issues. But by the time we got to issue # 4, it was officially the Silver Age of Comics.
