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 is in used (B-) condition; a moderate amount of toning, , a large tack hole at the top center, a hard 7" diagonal bend at 8:00, a fair amount of water damage/"mottling" in the lower half of the image, a 1" frayed tear at 11:00, edge creasing and tiny tears going all around the edges and a fair amount of surface wear (tiny dings, splotches, etc...) and a moderate curl to the paper- this is obviously a QUITE well-loved example. Still, this is one of the harder-to-find images in the series and the graphic design is just awesome. Check out this great informative list of shows (including this one) held at the Kaleidoscope in 1968:
