Astounding Tales! Five-Dollar Deal

Oh, here's the blurb:

"Astounding Tales! is a set of rules for mayhem, murder and Weird Horror set in the period between the 1920s and the end of the black-and-white B Movie era – Film Noir, hard-boiled novels, pulp magazines with Charles Atlas advertisements in the back, that sort of thing. A world where private eyes fight hoodlums, but where heroes – often cunningly disguised by wearing a small mask, which fools even their closest friends – save the world from ambitious mad scientists, laughably inept aliens and, quite often, the Germans. 'Astounding Tales' depends on a very fast pace, not worrying about details too much, and an attitude that says that heroes (and their sidekicks, dames and others in white hats) should have an advantage over thugs, punks, zombies and other minions of the Evil Overlords."
