(published by Fox Features Syndicate)
Big 3 was published by Fox Features Syndicate from Fall 1940 to January of 1942. It was an anthology title featuring Fox's three most popular characters at the time -- The Blue Beetle, the Flame, and Samson.
DC Comics now owns the Blue Beetle, but does not own any of the other features in Big 3. Therefore, the only stories that are indexed fully are the Blue Beetle stories.
