We can also see a sign for "Starr Pianos" on the extreme left and an advertisement for the "Alabama State Fair: Tickets For Sale Here". The sidewalks are busy and a policeman [?] stands in the intersection gazing at that new-fangled horseless carriage passing through.
We can also see banners that say simply "Salome." Are these advertisements for a performance of the Oscar Wilde play which originally premiered in 1891? Or perhaps the Richard Strauss opera from 1905? Or maybe it's a brand of soap available at Gunn's Pharmacy.
The pharmacy dates to 1895, when William Gunn bought the Ellis Drug Company. You can learn more about this business, and see a photograph of the interior, at the always-fascinating BhamWiki site.
