Exceptionally rare foldout postcard for Little Nemo at the Nixon Theater in Pittsburgh, PA. The Little Nemo comic strip was created by Winsor McCay, a pioneer in animation who produced the landmark animated film, Gertie the Dinosaur in 1914. The advertisement is done in an art nouveau perfected by McCay in the Little Nemo strip and features blurbs from several prominent New York newspapers of the time. The postcard measures 13x6.5" when opened.
