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 near mint to excellent (A-/B+ to B+) condition; aside from a tiny thin crease/bend in the lower left margin/corner, a trace of handling wear and a bit of edge toning with a couple of minuscule dings along the right margin, this example is just about as nice as they come.

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