Winsor McCay is one of the most highly regarded American cartoonists. In a survey by The Comics Journal, McCay's Little Nemo in Slumberland was named the fifth best comic strip or comic book of all time, ranking just behind George Herriman's Krazy Kat, Charles Schultz's Peanuts, Walt Kelly's Pogo, and Art Spiegelman's Maus. That's rare company. Of course, McCay also contributed to the development of animation with his pioneering work on "Gertie the Dinosaur" and other silent era shorts.
