1940 R146 Adventures of Superman card pair produced by the Leader Novelty Candy Co.  The pair includes #2 Smashing the Gangsters and #20 Through Granite Walls.  They are both in PR condition as they were issued as a perforated card panel along with a mail in prize coupon which has been removed.  They are both first series issue plain back versions without the Superman logo.  A rarely seen card pair.
