Making a baseball card is no easy task, and this set of progressive proof sheets for some cards from the 1977 Topps O-Pee-Chee baseball set shows just how complicated the process is. The 11 28-1/2" x 23" proof sheets detail what is added with each plate, beginning with a black and white sheet and ending with the final product. Included among the cards are a Ryan/Seaver Strikeout Leaders card and a Ryan Record Breaker card. The sheets show some corner and edge wear and are in excellent condition overall.
