Original 1st printing 18&1/2" diameter round concert poster for Iron Butterfly appearing with Life and Things to Come at the Kaleidoscope in Los Angeles, CA from 5/31-6/1/1968.
Design by Mike Salisbury/Eidos, Ltd., image is #14 in the Kaleidoscope series.
Medium-thick flat index stock poster has been professionally restored/rice-paper-backed to excellent (B+) condition; in addition to the aforementioned backing, there are a couple of tiny tack-hole fills, a hint of edge repair and a few stray pressed-out thin stress creases hiding within the image area, along with a bit of curl to the paper, but overall the piece looks absolutely FANTASTIC.
GREAT-looking example of one of the harder-to-find images in the series. Check out this great informative list of shows (including this one) held at the Kaleidoscope in 1968:
