Exceptional header card featuring four colored cards from the 1929-30 Exhibit issue and associated advertising copy, mounted on cardboard.  These header cards are quite desirable; this version features Hall of Famers Mickey Cochrane and Jimmy Foxx, as well as Lefty O'Doul. In well-worn condition, the header features corner clips at both lower corners, along with some notable paper loss on the advertising sign, particularly at the left.  Edge wear is clearly visible as well.  Still, an interesting piece comprised of four trimmed Exhibit 4-on-1 cards.
