Original 1st printing 17" diameter round concert poster for an "Independence Day Spectacular", featuring Spirit, the Kaleidoscope Orchestra and many more performing at the Kaleidoscope in Los Angeles, CA on 7/6/1968.
Art by Lanning Stern, image is featured in the Art of Rock book on page 280 (plate 3.80) and is #20 in the Kaleidoscope series.
Medium-thick flat index stock poster is in very good to excellent (B+) condition; just a soft thin horizontal fold/bend traversing the top of the image area (across "Spectacular" and a few almost invisible handling dings, otherwise fine.
FANTASTIC-looking example of one of the final images in the Kaleidoscope series.
