Vintage Phillips Milk of Magnesia Cobalt Blue Bottle — Chas. H. Phillips Chemical Co.

Vintage cobalt-blue Milk of Magnesia bottle embossed for the Chas. H. Phillips Chemical Company, with a metal screw cap.

The maker/product identification is supported by the photographed embossing. The previous c.1910–1925 date range is not retained without a bottle-form or closure chronology tying this exact example to those years.

Please review all photographs for embossing, cap, base, glass color and exact condition.
