I didn't think this would be needed, but I guess it is. This is the classic attached vs. detached earlobe. That is all you need. The overall ear shape is also very different.

This is another case of someone just finding an old photo, assigning a famous name to it and hoping someone will bite.

If you're not too good with the shape matching analytical approach, try thinking of it this way. See if you can find another known McGraw photo that isn't immediately obviously him. I've never seen one that isn't. If the photo in question isn't equally obvious, forget about it and save your money.
