This is not debatable. The match to Oswald, and the discordance to Lovelady visually screams at us.
Look at the perfect match of the ears between Oswald and Doorman. And the rest of the face , the eyes, nose, mouth, and chin match perfectly too, whereas Lovelady is a sea of discordance. His ears protrude, and quite severely. His head has a different shape. He is obviously a lot balder than Doorman. He looks very different, while Oswald is a spot-on match. It takes a whole heap of corruption not to see this.
