Really? Blondie? That makes sense for this scene.
You can tell because of the holster and the shirt is the same shirt Clint wore while he was being marched through the desert.

This is from a book, "Once Upon A Time: The Films of Sergio Leone" by Robert Cumbow. Since there's no caption for this photo, I don't know which production this is from. I assume it's from "My Name is Nobody." If you can tell, please let me know. And who is the guy with a soldier cap?
