1929 marked the beginning of the release of full four-on-one baseball sets by the Exhibit Supply Company, a practice they would continue well into the late 1930s.  This particular card includes Bernard Friberg, Lefty O'Doul, Fresco Thompson and Donald Hurst, and has been graded VG 3 by PSA, with an MK qualifier that addresses a small price, written near the stamp box on the reverse, in pencil.
