Guess Dumbos out too!
I have a film series call Mickey McGuire from the 20s-30s (this is early Mickey Rooney kids komedies)
It has a couple of black kids but the one name Hambone is Mickey Best Friend - yea he may be the butt of a lot of the sight jokes but there is nothing offensive to blacks in these short films that I can see (but hey im prolly blinded by White Privledge so what do I know)
