This article was first published in Collectables October 1998. This is meant to be a general guide by studio. A specific scene or episode from any era may be difficult to find, so consider being flexible with your collecting.
Disney fans are very lucky in that there is a lot of terrific art available to collect.
Courvoisier galleries mainly released pieces from Snow White, Pinocchio, Dumbo, Bambi, Fantasia, and some of the shorts- Ugly Duckling, etc. A lot of pieces were sold by the gallery, and therefore escaped being destroyed. A lot of the art has also survived due to Disney employees. Animators were allowed to take art home. I think of it as similar to notebook burning in university.
