Tribune caption on the back, Mar. 29, 1949: "Here's the keystone combination that will start for the Oaks tomorrow when the Acorns open the Pacific Coast League season in Sacramento. Eddie Samcoff (left), shortstop, tosses the ball to second baseman Billy Martin.- Tribune photo." Photo shows Martin at second base catching a ball that Samcoff has just tossed him. Both men are wearing their uniforms and mitts. The bleachers of the ballpark are empty in the background.
