As promised, here is an image of the Old Theatre, or the Southwark Theatre, which stood for many years on Cedar Street (now South Street) in Philadelphia. It caught fire in 1821, and was mostly destroyed, but it was somewhat rebuilt and used and a warehouse and a brewery. It lasted, in fact, to 1913, when it was finally torn down (see photo below).
Plumstead's Warehouse, which acted as the FIRST theater within Philadelphia proper in 1749, is thought to be depicted here, on the right of the group of three buildings, in this detail of a drawing of Philadelphia in the mid-18th Century:
