DC COMICS BACKING BOARD CARDS
(1987, 1989)

IN 1987, DC Comics tested the waters for trading card demand in the US market, but chose to release the product in a unique fashion: as part of backing boards for comics sold in three-packs at large retailers.
   Each card featured either a hero, a villain, or a "great moment in comics", and was labelled as such.
   The first set came in six different sheets of eight, with unperforated cut-out lines for the cards and a header for hanging the item.
   The Legion-related cards feature Tyr and the cover of ADVENTURE COMICS 307, which introduces Element Lad. The cover of CRISIS ON INFINITE EARTHS 1 was also used, which included Dawnstar.
    A second series comprising nine sheets was produced in 1989, but there was no Legion-related content.
