Winsor McCay was one of the giants of early comic strips. He began around the turn of the century with several strips. One titled Dreams of a Rarebit Fiend was something of a precursor to his most famous creation in that it was about weird dreams. Little Nemo in Slumberland was his tour de force. It had to do with a little boy, Nemo, in which his dreams would take him to wonderful places with unusual (to say the least) characters and fantastic events. I have a Nemo comic strip hanging on my wall which I bought 40 years ago.
The book is by Fantagraphis. Rick Marschall, the editor, gave me this book in 1992 when we were in Angoulême, France.

Winsor McCay also made the very first animated films, Gertie the Dinosaur being the best known. Read about McCay in his Wikipedia article. He was an absolute genius.
