George Sottung Childhood Days 16x20 1950's picture. (picture is in great shape backing insert not so much)I don't know much about this picture other than it seems to be old, the extra backing (seen in photos) has some kind of mailer on it. I did cover the back with a box so to not further damage the insert photo backing, I have seen this photo online from 325 to 799 but cant find the difference between this one and the others other than my has a mailer insert and no stamp on the back. The frame itself seems to also be vintage. Keep shop in mind I am not a photo expert and all is just opinion. Feel free to make an offer.
