1958 Topps #334 Mound Aces - Bob Friend / Billy Pierce
One of the nine multi-player combination cards in the 1958 set — the format Topps had introduced a year earlier with the 1957 Dodgers' Sluggers and Yankees' Power Hitters.
About this card
Topps paired two staff aces from opposite leagues on 1958 Topps #334, titled Mound Aces: Bob Friend of the Pittsburgh Pirates and Billy Pierce of the Chicago White Sox. The pairing fits a set known for expanded use of combination cards, and the card sits in Series Four, the run that opens at #265. Friend had just worked through a 1957 season of 14-18 with a 3.38 ERA for a Pirates club that tied for last at 62-92, yet he led the National League in starts with 38 and in innings pitched with 277, and his 17 complete games ranked second. Pierce, the left-handed anchor in Chicago, had been named the Sporting News American League Pitcher of the Year in 1957. It is a card for pitching collectors and for Pirates or White Sox fans, two clubs' number-one arms sharing one frame.
