Cobalt blue medicine bottle from Wm. R. Warner & Co., Philadelphia. Blown in a two piece hinge mold with tooled lip. Excellent+ condition, near mint. No cracks or chips, spots or lines seen in photos are simply mold anomalies typical of the glass manufacturing methods of the period. In business starting in 1856 through the war and beyond. Warner purchased the Baker Pharmacy in 1860 changing the name to that which appears on the bottle, c.1860-1865.
