The next animation art auction by Heritage Auctions will take place on June 16 and June 17, 2018. The catalog contains some truly spectacular items. Here are three of my favorites: Above are pieces by Eyvind Earle created for an abandoned Disney project from the late '40s and early 1950s about the history of jazz; below is a splendid concept drawing by Mary Blair from Alice in Wonderland; and at the bottom are some character designs for the Horned King from The Black Cauldron by Mel Shaw.
