This is a Real Photo Postcard. This one is impossible to date as the reverse side has no markings..only four lines for a address. I get a feeling that this photo is foreign. If it is not foreign it is from the East coast..we do not have fancy double doors like this in the Midwest and look at his moustache..it looks German to me. This couple do not look young enough to have small children..perhaps they are a favorite Uncle and Aunt..notice neither of them takes possession of the children like a parent would..their arms are behind their backs.
Thanks for stopping by, do come again:)
