In it’s day I bet this was really something to behold.
When I see this style I think NYC, or Miami, but not small town South Carolina.
I believe this was a clothing, shoe, store. A small department store design. I don’t know much else.
There is a second store further down the main street, same name. Both have probably been a dozen other businesses by now. At this point they are closed up.
If Main Street USA ever does see a resurgence I hope buildings like this get restored, not torn down for a square box with no character.
