March 22-23, 1967 at the Avalon Ballroom featuring Quicksilver Messenger Service, John Lee Hooker and the Miller Blues Band

“Based on the astrological reading on the date of the dance, this was going to happen during the retrograde of mercury. The picture of the band was taken at the De Young Museum in front a of a small Chinese sculpture of a rhino. I had to deal with a horizontal photo of the band and a vertical layout for the poster. He gave me the title ‘from the plains of Quicksilver’. Using the title, I thought of Mercury, so I made my letters into a planet and this letter form appears in a positive, negative, positive, negative. In other words when you read down, the lettering alternates. Because it is a circle, the photograph fit in perfectly, with no top or bottom.”
