Sixto Valencia Burgos (March 28, 1934, April 23, 2015) was a Mexican cartoon artist based in Mexico City, best known for taking over the responsibility of drawing famed Mexican cartoon character Memín Pinguín. This cartoon was very criticized by the USA media as it was considered racist because Memín, the main character, was drawn with a very gross black racist stereotype.
