I'm just curious what comic book racks were extant in the Golden Age.  My own research reveals the existence of racks (wire spinner, wooden shelf, and flat wire) by DC, Dell, and Ziff-Davis  [Correction: and King Comics and Classics Illustrated].  I've never seen a rack by any other publisher.  I'd love to increase my knowledge of this subject.  In the interest of sharing, here's some info on D.C. I believe the first D.C. comics rack came out in 1939 and featured seven slots for Action
