DRUG CO. 

BALTIMORE.

Bromo-Seltzer was invented in 1888 by Isaac E. Emerson and produced by the Emerson Drug Company of Baltimore Maryland.  It was sold in the United States in the form of effervescent granules that were mixed with water before ingestion. The product took its name from a component of the original formula,sodium bromide. Bromides are a class of tranquilizers that were withdrawn from the U.S. market in 1975 due to their toxicity. Their sedative effect probably accounted for Bromo-Seltzer's popularity as a hangover remedy...

Bromo-Seltzer's main offices and main factory were located in downtown Baltimore, Maryland, at the corner of West Lombard and South Eutaw Street...  Source: Wikipedia.
