We were researching illustrators recently, for a project we might be working on. Can't say much about the actual project but it could be amazing. While I was digging around, I remembered Eyvind Earle.
Artist, author and illustrator, you might know Earle's work for Disney from around the 50s; he worked on background illustrations and styling for things like Sleeping Beauty.
Earle died in 2000 but he left behind a stunning legacy of artwork. You can see lots of it here and watch a revealing autobiographical video. I think it's his serigraphs (screen prints) that are the most remarkable. Astonishing work.
