'Memin Pinguïn'.
Alberto Cabrera was the original artist of 'Memin Pinguin', one of the most popular Mexican comics. The series was created by the writer Yolanda Vargas Dulche, and first appeared in Pepin magazine in 1945. Cabrera was in charge of the art until 1963, when Sixto Valencia Burgos took over.
He should not be confused with U.S. basketball player Alberto Cabrera (1988).
