Santa's workshop from 1932.

of course the black doll would be a racist caricature instead of just black version of the white doll and of course Santa didn't teach the blk doll to say mama like the white one.

I just noticed that the OK stamp should be KO, because when Santa stamps the dolls it would come out as KO and not OK, but because it's a cartoon it comes out as OK anyway, even though it wouldn't realistically. It's a simple drawing mistake and observation.
