11 Negro League baseball cards from the Yesterday Baseball series in 1996, 10 of the 11 cards are signed. Yesterday Baseball was founded in 1996 by Dennis Biddle, a pitcher from the Negro Leagues who played for the Chicago American Giants in the early 1950’s. He founded the card company to help former Negro League ballplayers who had financial and health problems, and the stats of some of these players are incredible. Biddle was only 17 years old when he debuted for the Giants in 1953, and the youngest player ever to play in a Negro baseball league game. He injured his leg sliding into third in 1954 and that effectively ended his career. In that short two-year span, he won 30 games and lost 7, and gave up less than two hits a game - a staggering number. No pitcher in the major leagues has ever equaled or come close to that record. Joe Scott batted .714 in 58 games just after World War II broke out, well above Ted Williams’s average of .406 in 1941, another staggering record. The players in the series played for some of the most significant teams in the Negro leagues - the Kansas City Monarchs, the Birmingham Black Barons - as well as lesser known teams like the New York Black Yankees and the Zulu Cannibal Giants. The cards were not mass produced like cards by Topps or other big card companies, and the signatures here are all genuine. If you look at the two Biddle cards, they are not signed in the same spot on both cards, and if you look online and find the cards of any of these players, the signatures are in different places on those cards too, so the signatures appear to be genuine; three cards are also signed in pen, and the pen impressions go below the surface of the card, so these cards are genuine and not mass produced. We don’t know how many cards are in the series, but they were not mass produced, and in an interview he gave a couple of years ago, Dennis Biddle said only 56 players from the Negro Leagues were still alive, and 31 of them were over 90 years old. The cards come in plastic sleeves, and each card measures 3 1/2 x 2 1/2 inches. Please note that all sales are final. No refunds will be given under any circumstances.
