This vintage early-to-mid 20th century cobalt blue glass medicine bottle features bold embossed lettering on the front reading "MILK OF MAGNESIA" alongside the official circular trademark logo for "THE CHAS. H. PHILLIPS CHEMICAL COMPANY, GLENBROOK, CONN." Molded from deep blue glass, the bottle features an oval shape with a short neck and retains its original metal screw cap. Cobalt blue pharmaceutical bottles are classic collectibles, highly sought after for their vivid color and embossed detailing. The glass displays rich color depth with no visible chips or cracks. It shows light surface wear and heavy rusting on the original metal cap consistent with age.
