Disney - Alice In Wonderland 16 Field Animation Cel - Alice with Dormouse

This item is part of a large collection of Disney animation cel art we discovered in an abandoned storage unit in Southern California.
Many of the cels were stored in their original production folders.

About this item:
This item measures 16"x12.5" and is an single animation cel with production sheet.
The cel features Alice and Dormouse.
I am not sure if this is from the original motion picture, a story book or another production.
Production notes at the bottom read "new 19".
