Kellogg's Corn Flakes postcard features Cuban legend Adolfo Luque.
Up for auction at CubanBaseballCard in September 2010, it was postmarked March 23, 1948 and featured the stamping from the Association of Professional Baseball Players of Cuba.
Elected to the Cuban Baseball Hall of Fame in 1958, Luque played for Fe, Habana, Almendares, Orientales, Alacranes and Cienfuegos in 23 winters -- 14 with Almendares -- in Cuba from 1912-45.
He ranks first in Cuban League history in seasons pitched (22) and second in wins (106), according to Who's Who in Cuban Baseball, 1878-1961. Seven times he led the league in games won.
In 30 seasons as a manager, Luque ranks second in Cuban League history behind Miguel Angel Gonzalez in victories (705) and pennants won (11).
In 20 major-league seasons, Luque compiled a 194-175 career record with a 3.24 ERA. His best season came in 1923 with the Cincinnati Reds. After losing 23 games despite a 3.31 ERA the previous season, Luque (left) led the National League with 27 wins (eight losses), a 1.93 ERA and six shutouts.
