I have a pair of black buster boots with the stamp. They're more of a lug sole work boot aesthetic so the stamp doesn't bother me too much. Also it doesn't seem to show up as much on the black. But the stamp is on the outside of the heels so I don't see how it could be more visible to others short of being on the toes. It's not as visible to you the wearer however.
I've seen Yorks and Pinkertons with the stamp. It just looks wrong. Keep looking. I think they still make non Red Ear Yorks.
