Is this the old wagon yard at or near Wynnewood, Oklahoma?

       This old photograph was sent by Sandra VOSSLER whose step-great grandfather, James Washington CARROLL worked in a wagon yard at or near Wynnewood, Oklahoma about 1918/20. He was married to Sandra's great grandmother, Maggie Baucom Caves CARROLL.

       There is nothing written on the back of the photograph to identify the scene but Sandra believes it was taken in the teen's or early 1920's in Oklahoma.
