These ten black and white images, each measuring 3 ? x 5”, were promotional photos for the sports company MacGregor/Brunswick, whose “advisory staff” included such baseball luminaries as Roberto Clemente and Willie Mays, as well as Tony Oliva, John Edwards, Ron Hansen, Al Downing, Zoilo Versalles, Deron Johnson, Claude Osteen, and Bobby Richardson. Very rare and representative of that era.
