One can't see too many of these! How about this sweet Thirteenth Floor Elevators Vulcan Gas Company poster! This puppy is up on Ebay, right now, with a price of four thousand. I wonder what mine, signed by 'Elevators, Conqueroo & Shiva's members, would bring? Annnnnyway, this is sweet!
Take a look at Gilbert Shelton having a beer at the top!
