I'd like to shed some light on this photo. It was taken in Springfield, MO and I have wondered all my life why you would name a flea market S.T.D. . . I finally found out a few months ago. The building the original flea market (there are several in town) was originally Springfield Tool and Die. It was a manufacturing plant of some kind. When the company when out of business an individual who worked there bought the building but kept the name! So glad to see this photo finally on here.
