I'm beginning a new series, all about two of Alice's forgotten characters in the world of Disney, the Gryphon and the Mock Turtle.
All throughout the development of Alice in Wonderland, Disney struggled with how much of the two books to include in the final product. As such, all the original Carroll characters (and a few new ones) received at least some treatment. Two of those characters were the Gryphon and the Mock Turtle.
These are original stills that were used as reference - presumably for story development - enlargements of the original Tenniel illustrations of Alice with the Gryphon and the Mock Turtle. I found these with a large bunch of story stills from the estate of a former Disney employee. There were 34 of these Tenniel illustration stills, along with additional stills of story art.
