NOTE we have been made aware of a PSA labeling error with this card, which is actually a 1931-32 Exhibit 4-on-1 card and not a 1933. This is an orange-on-white example with a redemption offer and coupon on the reverse, the card front featuring Hall of Famers Jimmy Foxx, Mickey Cochrane and Lefty Grove, along with George Haas.  A strong card with exceptional eye appeal for the grade.  The reason for the MK qualifier assessed by PSA is not immediately clear; a small abrasion can be seen in the area near Foxx' cap, and some surface discoloration can be seen near the brim of Grove's cap.  The qualifier could also be related to the darker markings in the left and right border areas of the card.
