Winsor McCay, for those that don't know the name, was a comic strip author in the early twentieth century. While reading up on him, what I found in the Wikipedia is typical. It states all the many, many artists and writers he's influenced through the years (including Maurice Sendak, for example), but I can't find references to what his inspirations and influences were.
Both Little Nemo and Dreams of a Rarebit Fiend were stories about dreams. (Little Nemo was originally in Little Nemo in Slumberland and later in In the Land of Wonderful Dreams.) Little Nemo fell asleep each night and went on an adventure and awoke the next morning. The later was about the phantasmagoric nightmares of people after eating Welsh rabbit (rarebit) or other unusual dishes. Both strips were quite fantastical and Little Nemo, especially, visited some amazing fantasy settings in dreamland and McCay experimented with interesting arrangements of the panels in his strip.
While it's easy to find out who claims to have been inspired or influenced by McCay, I've wondered for years what inspired and influenced him. Is there any record of what influenced his work with Little Nemo or Dreams of a Rarebit Fiend?
