NAME THE FILM - Art Corner Background

I've never done this before, but I have a hunch my readers can help out! This is an Art Corner print BG from an unknown Disney film.

Does anyone recognize this BG? Can you tell me the title of the film from which it originated?

The style looks Mary Blair-esque to me, but the color palette doesn't. Usually the Art Corner used readily recognizable BGs from Sleeping Beauty and 101 Dalmatians, but this one has me stumped.

(Those cel paint remnants of Dale are from the Disney Ink and Paint Department. The cel has been restored.)
