One of the earliest clips in this collection is a 2-minute fragment, which is all that survives from a lost 1921 film called “The Centaurs” by Winsor McCay (USA: Rialto Productions). McCay was a comics illustrator, vaudeville performer and early animation pioneer, best known for his comic strip “Little Nemo in Slumberland”. His very fine linework, naturalistic depiction and focus on the female figure clearly influenced Disney’s Centaurs in “Fantasia” twenty years later.
