A terrific Vintage Listerine Bottle produced by Owens Illinois Glass Company for the Lambert Pharmacal Company. The Listerine Bottle measures 4 1/4 inches tall with a bottom diameter of 1 3/4 inches. The bottle is marked on the bottom with the Diamond superimposed over an oval [letter O]. The numbers on the bottom are 7 for the Alton, IL factory, number 7 with a dot to represent the mold and the number 2 for the date. There are no chips or cracks that I can detect. The inside is in need of cleaning.
