Recently I bought this very unique and rare 1970 50th Anniversary Overmyer Mould Company bottle. It was made for them by the Hillsboro Glass Company in Illinois. The factory existed from 1961-1997. They were actually a subsidiary of Hiram Walker & Sons Distilleries and for this reason, most bottles made there were amber in color. So it's no surprise that this bottle is also amber. The Overmyer Mould company crafted molds for most of the major players in the glass industry including Anchor Hocking Glass and then later Anchor Glass Container. The bottle is even listed in the Anchor Hocking Commemorative bottle book, with a value of $450.00 to $500.00 if it has the small Overmyer company brochure that came with it. Unfortunately I don't have that but the bottle is enough for me.
