Disney created educational panels like these off and on to help promote a new upcoming animated feature. They were hung in the main hallway of the animation building, ground floor, or at the movie theatre where the film premiered.
I recall seeing Steps in the Making panels for Sleeping Beauty, The Aristocats and The Rescuers.
For The Jungle Book the character of King Louie guides you through the animation process.
Sketches by Ken Anderson, storyboards, and animation drawings by John Lounsbery and Frank Thomas help explain how Louie makes it from early development to final cels on to the screen.
All pretty basic stuff, but still lots of fun to follow nevertheless.
Milt Kahl is featured in the photos, and yes, I do own his animation desk.
