This antique embossed bottle measures 8 1/2 inches tall and features the chemical formula for sulfuric acid (H2SO4) and the abbreviation for concentration (Con) on the front. It's a rare find for collectors of apothecary and pharmaceutical antiques. With its connection to the history of science and medicine, this bottle would make a unique addition to any antique collection. It does have Maker mark on the bottom of the bottle ? I just don't know it. Very large come with a stopper but not original stopper
