Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

Now, I want you to look at the backs of their necks. And I put arrows, since you have trouble seeing things. Do you notice on the left that the impostors hairline was high and horizontal, and his neck below it was razored clean? And do you notice that Ruby on the right has got a scruffy neck due to hair growth that all the way down to his collar? Just compare the areas to which the arrows are pointing.
