Here is an image that I swiped from the Grove City Historical Society web site. It shows "The High Bridge Pharmacy". The photo information says it was at the corner of North Broad and Chestnut Streets. More importantly, in the background is a Sterling Gas Station. Quaker State used to be Sterling Gasoline, and Schall's used to be a Quaker State gas station! My quess is that this picture was taken sometime between 1930-1950.
