These drawings didn't make it into the Jungle Book exhibition. We had so much great material, we could not include all of it. Most of these Milt Kahl "outtakes" are sketches made for other animators.
Colonel Hathi for John Lounsbery, King Louie and Baloo for Frank Thomas and the Girl for Ollie Johnston.
As Milt proclaimed in an interview:"I was the Disney style!"
