The 1922 Eastern Exhibit Supply issue generally feature postcard backs.  Produced by a Philadelphia company, the cards are often mistaken for traditional Exhibits, and in some cases, the Philadelphia company name has been blacked out from the reverse and replaced with the Chicago Exhibit company name.  Typically, the cards are printed with brown ink on the reverse, though in this more scarce example featuring Hall of Fame catcher Ray Schalk, the ink is black.  The card has been graded AUTHENTIC by SGC, a large hole apparent on the lower-right.  The card is well-worn, more desirable for the print anomaly than for the condition.
