I did have some 1956 baseball cards when I collected back in Delphi, but I do not remember having one of Aparicio. That may be because I really did not get interested in the White Sox and Little Looie until 1958.
Aparicio's debut came on April 17, 1956. He put together a very impressive rookie season for the White Sox. He appeared in 152 games while collecting 147 hits, scoring 69 runs and putting up a .266 batting average. As a preview of what was to come, Aparicio led the league with 21 stolen bases. Aparicio won the Rookie of the Year Award easily beating out both Rocky Colavito and Tito Francona.
