An old Sinclair sign in front of this former gas station, now a restaurant,
in the 4700 block of Camp Bowie Blvd., Fort Worth, Texas.
The fenced in area is the former pump area that is now the outdoor seating area.
Evidently, the owner is a Sinclair fan as the building had quite a few other signs on it.

In 1969, Sinclair was bought by ARCO, and these signs appeared to alert people
that the name was changing.
This photo was taken sometime in 1970 by Walt Wimer.
It was located in Wooster, Ohio, probably on US 30 on the west edge of town.

Here I attempted to zoom in on the sign changing artwork on Walt's photo above.
