5-5/8x8-5/8" stiff paper card promoting 1948 Columbia serial starring Kirk Alyn as Superman. Great Golden Age DC Comics art image of Superman appears beside his comic book title logo/name. Image bears 1948 National Comics Publication, Inc. copyright. Text reads "A Decided Plus For Any Theatre...Anywhere! The One And Only Superman...Serial Scoop Of Scoops! 10 Years...A Comic Book Standout! 9 Years...A Nation-Wide Newspaper Feature! 8 Years...A Radio Sensation!

Promotional card was obviously aimed toward theater management, reverse of card bears Columbia Pictures Corporation return address and bears typed address to "Manager - Relax Theatre."
