Two hundred different players are included in this set, but with variations the number of different cards exceeds 350. Cards were issued singly and in various panel configurations on the backs of cereal boxes, as well as on thinner stock in 10-card team sheets available from Post via a mail-in offer. Because of placement on less popular sizes and brands of cereal, or because they were issued only on box backs or company sheets, some cards were issued in significantly smaller quantities, making their prices much higher than other comparable players in the set. Well-cut individual cards cards measure about 3-1/2" x 2-1/2". All cards are numbered in the upper-left corner. Card fronts have full-color portrait photos of the player, along with biographical information and 1960 and career statistics. Backs are blank. The complete set price includes only the most common variation of each player. - 2006 Standard Catalog of Baseball Cards, 15th Edition.
