Found in Atlanta in the 70s. Since the label is so intact I can't imagine it would be much older than that.
I think it has the Owens Illinois makers mark.
The general style of the ACL and bottle makes me think late 1950s to early/mid 1960s. I find lots with similar styling in a dump that I frequent, which was used from 1947-62(ish). I don't know anything about BeauRegards Beverages in specific, though.
