Pulled from my collection, I've had this bottle for more than 20 years. There are several variant Halls in squats and sodas, and this one is PHILA rather than PHILADA and is unembossed on the reverse. It has an applied double taper top, and a robust pontil scar.
Embossed: P. HALL / PHILA
Height: 7 1/2"
Color: deep bluish green
