Mickey Mouse isn’t like a minstrel; he is a minstrel.
"There was an interesting bit of development there. They drew [Mickey Mouse] with black hands on the black arm against the black body and black feet. And if he said something in here (gestures in front of body), you couldn't see it and won't realize. Fairly early they had tried it on him, putting the white gloves on him here, and the white shoes, but it had to clear up." ~ Frank Thomas
The characters were in black and white with no shades of grey to soften the contrast or delineate a form. Mickey's body was black, his arms and his hands- all black. There was no way to stage an action except in silhouette. How else could there be any clarity? A hand in front of a chest would simply disappear.
