This poster, created by Wes Wilson in 1966, promoted a concert at the Avalon Ballroom in San Francisco. Headliners were The Great Society and Blues Project. Here we have the original printing of this poster. It’s part of the Family Dog series of concert posters, organized under promoter Chet Helms. This poster measures approximately 14×20 inches. Fair to good condition on this piece. Note two significant creases across the poster, along with edge wear. There are several dark stains on the back and abrasions on the front of the piece as well. The original colors are still nice.
