This is a series of stills of David Hall storyboards of Alice leaving the pool of tears and encountering the Gryphon and the Mock Turtle on shore.
In this detail you can see the Gryphon in a very similar pose as one of the Tenniel illustrations from yesterday's post.
This is a very nice portrait of these two characters, I particularly like the Gryphon's bowler hat.
Here it appears as though the Caucus Race is beginning, with Mock Turtle and Gryphon taking part.
These stills came from the estate of Jack Cutting, Disney Foreign Agent (I love that title, sounds positively mysterious), and was part of a larger group that essentially covers the entire story arc.
