Winsor McCay's Little Nemo animation entered into Library of Congress Registry, reports the Associated Press on the Washington Post website.
The Library's press release says:
Little Nemo (1911)
This classic work, a mix of live action and animation, was adapted from Winsor McCay’s famed 1905 comic strip "Little Nemo in Slumberland." Its fluidity, graphics and story-telling was light years beyond other films made during that time. A seminal figure in both animation and comic art, McCay profoundly influenced many generations of future animators, including Walt Disney.
This is not the 1990s Japanese animation of course. Speaking of McCay, I had an original of one of his political drawings in my hands this weekend. Hoo-hah!
Another cartoon I'm not familiar with was added as well:
Quasi at the Quackadero (1975)
"Quasi at the Quackadero" has earned the term "unique." Once described as a "mixture of 1930s Van Beuren cartoons and 1960s R. Crumb comics with a dash of Sam Flax," and a descendent of the "Depression-era funny animal cartoon," Sally Cruikshank’s wildly imaginative tale of odd creatures visiting a psychedelic amusement park careens creatively from strange to truly wacky scenes. It became a favorite of the Midnight Movie circuit in the 1970s. Cruikshank later created animation sequences for "Sesame Street," the 1986 film "Ruthless People" and the "Cartoon Land" sequence in the 1983 film "Twilight Zone: The Movie."
