4622 a John Graf Milwaukee, Wis. (TBADE error)

I love this antique soda bottle! It has a subtle error on the reverse side embossing. Where it should say, "TRADE MARK", it says, "TBADE MARK". The entire embossing reads, "JOHN GRAF MILWAUKEE WIS." on the front and, "THE BEST WHAT GIVES TBADE MARK THIS BOTTLE NOT TO BE SOLD" on the reverse. This minty example is crude (it leans forward), has a mug-base (8-sided arches upward), and stands about 6 & 1/4 inches tall.
