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; really nothing more than a few semi-soft handling creases and hairline-thin stress bends scattered around the image/outer margin area and a small pressure crease in the upper left margin, otherwise it is a VERY sharp/mostly-clean 1st printing example of this always-in-demand Rick Griffin Family Dog image.
