The tobacco card set known as T206 was issued from 1909 to 1911 in cigarette and loose tobacco packs through 16 different brands owned by the American Tobacco Company. It is a landmark set in the history of baseball card collecting, due to its size, rarity, and the quality of its color lithographs.
The name T206 refers to the catalog designation assigned by Jefferson Burdick in his book The American Card Catalog. It is also known informally as the "White Border" set due to the distinctive white borders surrounding the lithographs on each card.
The T206 set consists of 524 cards. Over 100 of the cards picture minor league players. There are also multiple cards for the same player in different poses, different uniforms, or even with different teams after being traded (since the set was issued over a period of three years). The cards measure 1 7⁄16 by 2 5⁄8 inches (3.7 cm × 6.7 cm) which is considered by many collectors to be the standard tobacco card size.
The T206 set is the most popular and widely collected set of the tobacco/pre-war era. The historical significance of the set as well as the large number of variations give it enormous appeal to collectors. In addition, the set features many Baseball Hall of Fame members including Ty Cobb (who is pictured on 4 different cards), Walter Johnson, Cy Young, and Christy Mathewson. The value of the cards has led to a great deal of counterfeiting over the years. The T206 Collection: The Players & Their Stories by Tom and Ellen Zappala and Peter Randall Publishers highlights the personal and professional lives of the players in the collection and discusses the values of the cards as well as the mystique behind the collection.
