Frost Amphitheatre, Stanford University 8/9/69

This obscure poster is from the Frost Amphitheatre at Stanford University and was used to advertise a show by Quicksilver Messenger Service. It is a great-looking poster and seems to be quite rare — in fact, the one we offer here is the only one we have ever seen! While this is really a piece for the advanced Quicksilver collector, the design is one that anyone can appreciate.

The original poster was printed on white vellum and measures approximately 22⅜″ x 17⅜″.
