Thanks for posting this. I have to agree with you, not being clear makes it difficult to tell. Your right about the height of Elvis at 13. When he was fully grown he was 6 foot. The person looks to be the same height of everyone else. Is that a hat on his head or the shadow? I know there is that picture of him when he was 13 or 14 with a smilar jacket on.
Also, I can't imagine Elvis getting his picture taken with out standing next to his parents. Is that Gladys with the hat on? I don't think I have ever seen her wear a hat in any picture. Maybe she wore one to church.
If they are real this is a great find.
