The 630-card set was produced in 1975 by the Sport Star Publishing Company, but not released until 1976. The cards were numbered by team, with the Phillies comprising cards 456 through 476. (A few Phillies prospects show up at the end of the set). One card I don't have from this set, that I'd like to eventually track down: card #622 features former Phillie Dick Sisler as a coach for the San Diego Padres.
Did You Know?: According to Beckett's 16th Baseball Card Price Guide, "The card backs were edited by Keith Olbermann, prior to his ESPN broadcasting days."
