Pannell Bros, Staunton VA
A postcard I saw on eBay was postmarked 1908, and depicted the interior of the Pannell Bros. Drug Store. It depicted African Americans, so presumably the Pannell brothers were African American.
(more information will be added when I get around to researching this druggist)
The sizes of these clear bottles are 6.8" (8oz), 5.5" (4oz), 4.5" (2oz), and 3.7" (1oz).
They're all embossed the same, except for the number of ounces (viii, iv, ii & i)
and the letter between the "W T & CO" and the "U.S.A." on the base.
