The cards in this 108-card set measure approximately 2 3/8" by 2 7/8". The Diamond Stars set, produced by National Chicle from 1934-36, is also commonly known by its catalog designation, R327. The year of production can be determined by the statistics contained on the back of the card. There are 170 possible front/back combinations counting blue (B) and green (G) backs over all three years. The last twelve cards are repeat players and are quite scarce. The checklist below lists the year(s) and back color(s) for the cards. Cards 32 through 72 were issued only in 1935 with green ink on back. Cards 73 through 84 were issued three ways: 35B, 35G, and 36B. Card numbers 85 through 108 were issued only in 1936 with blue ink on back. The complete set price below refers to the set of all variations listed explicitly below. A blank-backed proof sheet of 12 additional (never-issued) cards was discovered in 1980.
