This poster was produced in 1981 by the Anheuser-Bush Company of St. Louis, MO and features an atmospheric unfocused view of Stonehenge constructed from Michelob beer bottles. I have not been able to find any information about this ad campaign. Any additional info, like where and why, would be appreciated.
Although this poster is not in very good condition, it is the only one I have ever seen. Seriously it is unlikely this is the last surviving copy, just the only one I have found.
