Last week I purchased a RPPC from a seller in Iowa hoping that it would turn out to be a distant relative of mine. I haven't located anyone by that name in my line/tree. On the front along the lower left of the photo side is written "Me age 4 Taken before we left Tenn." The postcard was never mailed and on the back is written "Mable Pryor."
I did some research and the postcard is from 1904-1918, which would make the child born between about 1900-1914.
