This just in from Gunnar:

[I just found this rather exeptional piece of art on ComicArt Fans:

From description:

Story Painting for Winken, Blinken and Nod, 1938

Signed pre-production artwork from the Disney studio is very rare. This exceptional painting in watercolor and guache is signed by Emil Flohri, who worked for Disney from 1929 until 1938. It is painted on paper similar to that used for background paintings and is rather large for story art -- 9 X 11 inches.]
