The 1931-32 Exhibit 4-on-1 cards are distinguishable by their coupon backs, which list different premiums made available by redeeming coupons clipped from the bottom corner of the card.  The redemption makes the issue condition-sensitive, as collectors were encouraged to clip the lower corner for the redemption offer.  Cards were printed in a variety of color combinations, including black on green, blue on green, black on orange, black on red, blue on white and black on yellow.  There were 32 cards in the set.

Green tinted example featuring Hall of Famer Dazzy Vance along with popular should-be-Hall-of-Famer Lefty O'Doul.  Though the card presents well, the POOR assessment from PSA relates to a pinhole and related tearing near the top center of the card.
