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; aside from a tiny pressure crease/nip in the lower left margin/corner, a trace of handling wear and a hint of edge creasing along the right margin (a couple of tiny thin bends), this example is just about as nice as they come.

 An absolutely SUPERB-looking 1st printing specimen of this oft-requested Griffin image.
