I wish there were more books of Evyind Earle's art out there- everything's out of print!
He was the art director for Disney's Sleeping Beauty, but also an accomplished mid-century artist/ illustrator.
Here's an interesting article about his work at Disney- apparently he wasn't so liked by the 9 Old Men, but Disney had faith in Earle's unusual and striking production design.
I love his drawings for a lot of the same reasons that I like Dulac (content, colors, and Art Nouveau style), but Nielsen brings in a slightly more Asian aesthetic- he was apparently influenced by Japanese woodprints and Hiroshige.
