This product was sold by J. W. Colman and Co., of Owensboro, Kentucky. I found J. W. Coleman worked at Conway's Drug Store in 1864. He must have become the Proprietor some time after that. In 1883, it was called J. W. Coleman & Co.'s Drug Store. This bottle is probably from the late 1860s, so he must have become the Proprietor around that time.
