Superhero Collection At Mafia Wars

The Superhero Collection at Mafia Wars, a Facebook game, features seven comic books that can only be received from red and blue mystery bags. I have not received any yet in my collection but the characters include Arachnid-Man (Awesome Fantasy), Squirrel Man (Sleuth Comics), Superbman (Superb Comics), Freak Squad, Blue Beacon (United States Comics), General USA and Terrific Titan.

You can clearly see that Sleuth Comics and United States Comics are featured on the Blue Mystery Bag icon.
