It's totally obvious that's blackface. His lips are too narrow, his nose isn't wide and flat, and his cranium is too large. His eyes are the wrong color and look intelligent. He doesn't look terribly jewish though. More like an ugly white guy. His cheekbones are high and his forehead is pronounced, not slanted back. His nose is crypto-jewish, just barely extending below his nostrils. His ears are totally jewish though.
