Yep. Every time Tom gets caught in an explosion he turns black. Racist for sure.
There is one where Jerry leaves the country for the city. He ends up in Grand Central and gets pick ed up by the shoe-shine guy and gets his head dunked in black shoe polish and comes out in “black-face”. Yeah...that one’s a little on the edge of it, other than it’s just a smile. But, the black-face schtick was the gag, and the same scene where the black-face part is edited out, just doesn’t work.
