The 1977 Topps Baseball set consists of 660 cards, each measuring 2-1/2" by 3-1/2”. A color photo of the respective player and his facsimile signature dominates each card, with the player’s name and team printed at the top border. A small pennant, depicting his position, appears at the upper right corner. Subsets include League Leaders, World Series, Turn Back the Clock, Big League Brothers, and Rookies – with Bruce Sutter and Lee Mazilli among the most prominent entries in the latter category. Among the other most desirable entries is the final active player entry for Brooks Robinson, as well as stars future Cooperstown members Mike Schmidt, Nolan Ryan, Bruce Sutter, and a Strikeout Leaders card (#6) featuring Ryan and Tom Seaver.
