Original 1st printing 13 x 22&1/4" concert poster for Spirit appearing with the Sir Douglas Quintet and Notes from the Underground at the Avalon Ballroom in San Francisco, CA from 8/23-25/1968.

 Art by Stanley Mouse (with a photo by Arnold Genthe), image is # 134 in the Family Dog/Avalon series.

 Medium flat index stock poster is in fantastic mint to mint/near mint (A/A- to A-) condition; aside from a tiny corner bump or two, it's pretty much as sharp as they come.

 As an added bonus, this example has been HAND-SIGNED (in pencil) by Spirit lead singer/guitarist Randy California (1951-1997).
