The 1991 Score baseball set consists of 893 cards, each measuring 2-1/2" by 3-1/2”. Score released its 1991 edition in two series of 441 cards and 452 cards each – the first time the company went the two-series route with a major set. The card fronts feature a full-color player image framed by one of four borders – black, blue, teal, or white. His name, team name, position, and the Score name also are printed on the front. Backs include standard biographical and statistical data. Ken Griffey, Jr. (#2), Ryne Sandberg (#3), Nolan Ryan (#4), Cal Ripken, Jr. (#95), George Brett (#120), Barry Bonds (#330), Rookie cards include Mike Mussina (#283) and Chipper Jones (#671). The edition includes a wealth of subsets that include Rookie Prospects (#s 331-379), First Draft Picks (#s 380-391 and #s 671-682), American League All-Stars (#s 392-401), National League All-Stars (#s 661-670), and Award Winners (#s 875-881). Card #737 featured an American flag designed to honor American armed forces involved in Desert Storm. Twenty-two cards in the set, each representing a pitcher, have incorrect data identified on the reverse. In each case, their “Innings Pitched” totals do not equal the added year-by-year total. A few other cards have misspelled names or incorrect places of birth. None of the error cards, however, command a premium price.
