Original 1st printing 14&1/4 x 20" concert poster for Quicksilver Messenger Service appearing with the Sons of Champlin and Taj Mahal and the Blue Flames at the Avalon Ballroom in San Francisco, CA from 10/27-29/1967.

 Art by Rick Griffin, image ("Sunday Funnies" or "Mornin' Papa") is # 89 in the Family Dog/Avalon series.

 Medium flat index stock poster is in excellent (B+) condition; just a tiny 1" diagonal bend in the lower left margin/corner, a few tiny diagonal streaks/smudges along the bottom margin, a couple of ULTRA-tiny bends/pressure creases along the left/right (mostly right) margins, a trace of edge toning and a whisper of handling wear, otherwise fine.

 A FANTASTIC-looking 1st printing specimen of one of Rick Griffin's most popular Family Dog images.
