4610 a John Graf Milwaukee, Wis.
This antique soda bottle comes from the same mold as the citron bottle shown next to it (in the gallery). I think that this is a transitional bottle between the early Wisconsin glass molds and those that follow. The bottle is mug-based (six-sided arches upward), blue aqua, and stands 6 & 3/8 inches tall. The embossing reads, "JOHN GRAF MILWAUKEE WIS." on the front and, "THIS BOTTLE NOT TO BE SOLD" on the reverse.
