so these photos are obviously gorgeous. I don't know squat about the dates of original photos or type. I believe these "poses" are from the "1951" season which the patch indicates.
The only time I have ever seen the photo on the right is associated with a long line of FAKE SIGNATURES with that photo from the 1980s. This is a similar ERA photo albeit with what I believe is a rock solid "Cadillac" Mantle signature with Inscription taken with the same uniform and patch.
I heard the patch was cut into a million pieces to make fake PMG patch triple lundy relic cards.
I hope someone else knows some more about them because they are indeed beautiful as they sit like that.
