Original 1st printing 19" diameter round concert poster for Quicksilver Messenger Service appearing with the Flamin' Groovies and Kaleidoscope (featuring David Lindley) at the Kaleidoscope in Los Angeles, CA on 4/21/1968.
Design by Dahlgren/Eidos, Ltd., image is # 9 in the Kaleidoscope series.
Medium-thick flat index stock poster is in excellent (B+) condition; just a few scattered handling/pinch dings and few small bends around the outer edges and a series of thin tape pulls on the reverse, otherwise fine.
Very bright original 1968 Kaleidoscope poster, one of the only posters in the series to feature a photo of the headlining band; check out this great informative list of shows (including this one) held at the Kaleidoscope:
