Original 1st printing 22&5/8 x 16&1/8" concert poster for Spirit appearing with Blues Image and Harvey Mandel from 11/27-30/1968, and the Turtles appearing with Harvey Mandel (KPFK-FM broadcast) on 12/1/1968, all shows held at the Bank in Torrance, CA.
Art by Robert A. Wilson, this example has been HAND-SIGNED (in black sharpie) by Harvey Mandel.
Medium-thick flat index stock poster is in very good to excellent (B/B+ to B+) condition; just a bit of creasing/wear and a few light stains in the top margin, several thin diagonal creases in each of the four corners, a few VERY well-camouflaged thin bends and handling dings hiding within the image area, a stray pin-prick surface stain or two and a couple of relatively minor edge dings/thin creases, otherwise fine.
SUPERB-looking PERFORMER-SIGNED example of this unusual image from the Bank series. For a closer look at the history of the Bank (complete with first-hand reader commentary), read HERE:
