Carter was a coach for the Phillies in 1959 and at the beginning of 1960, resigning in late May due to poor health. His picture in the Coaches Pack is a "floating head" shot cut from a Topps card, but I found something a bit better:
Presumably from Spring Training, 1959 (Eddie Sawyer had replaced Mayo Smith as the Phils' manager during the 1958 season, and finished the season with Smith's coaches, then brought in a whole new crew for 1959) although Carter looks somewhat unwell, so perhaps it's 1960, after all.
