Little Nemo in Slumberland was a full-page weekly strip written and drawn by Winsor McCay. It depicted Little Nemo having fantastic dreams that were interrupted by his awakening in the final panel. The strip is considered McCay's masterpiece for its experiments with the form of the comics page, its use of color and perspective, its timing and pacing, the size and shape of its panels and its architectural and other details.
Little Nemo in Slumberland ran in the New York Herald Tribune from October 15, 1905 until July 23, 1911. The strip was renamed Little Nemo in the Land of Wonderful Dreams when McCay brought it to William Randolph Hearst's New York American, where it ran from September 3, 1911 until July 26, 1914. When McCay returned to the Herald Tribune in 1924, he revived the strip and it ran under its original title from August 3, 1924 until January 9, 1927, when McCay returned to Hearst.
