Here's a very nice first printing of BG-35, the classic Wes Wilson designed poster for the great Muddy Waters and his Blues Band with Quicksilver Messenger Service at San Francisco's Fillmore Auditorium, in November 1966. This 13 3/4" x 22 1/2" poster was originally folded in quarters by legendary San Francisco music critic Ralph J. Gleason (see below) to fit into his famed trench coat, but unfolded and stored flat for 43 years since the concert. While folded the poster was gently creased twice, resulting in two light creases in each corner–the photo represents them accurately. There is a tiny bit of what looks like ink on the left edge 3" from the bottom, but otherwise this is crisp and fresh, having never been hung or exhibited–in fact, it's sat in a pile for 43 years since the show. A clean fresh first printing of a rare one ! This poster comes the collection of the late Ralph J. Gleason (1917-1975;) one of the most influential jazz and pop music critics of all time. He was a central figure in the San Francisco rock scene, helped organize the Monterey Pop Festival, and co-founded Rolling Stone magazine. Bill Graham himself credited Gleason with suggesting the Fillmore Auditorium to him as a site for concerts, while the Family Dog met with Gleason at his home to discuss their idea to stage dance concerts, prior to their first show at the Longshoreman's Hall. This is a rare opportunity to obtain a poster from the personal collection of one of the key figures of the San Francisco Scene. On request, we will gladly provide a certificate of authenticity stating that this poster came from the Ralph J. Gleason Collection.
