Back in the mid 90's I worked for an animation gallery in Philadelphia part time. I would trade my time, and artistic abilities, painting backgrounds for animation collectors to display their cels over, for credit towards animation sketches, production drawings, and production cels.The cels are from the non-Disney animated film, "Watership Down," one of my favorite movies of all time. Due to the exorbitant prices that Disney animation art demanded in the 1990's, I only have a few Disney production drawings, and this one sketch of Mickey Mouse:
She would pick out discarded drawings from the trash, bring them home, cut them out, and paste them in a book.
I was drawn to this because, while I have no way of knowing absolutely, it sure looks like a Brave Little Tailor Mickey, to me.
