The back of this real photo postcard indicates this is possibly Jack Dicaslito, or it could have been sent to Jack. The exact text is:
B. F. Rudd
Green Forest, Ark
The city there could also possibly be Drum Forest or Rain Forest, but I’m leaning toward Green Forest. The postcard itself doesn’t have any of the nice stamp box insignia that helps date these postcards. My guess is it was somewhere between 1910-1930.
