Art by Gary Grimshaw, the image is # 20 in the Russ Gibb Presents/Grande series and is featured in the Art of Rock book on page 243.
Medium-thick flat index stock flyer is in good/decent (B to B/B-) condition; there are a number of tape residue marks and a couple of surface pulls around the outer margin area and in each corner (and one mark in the bottom center margin), along with a small tear in the top left corner, a series of small surface scuffs/dings, a flattened horizontal center crease, light handling wear/creasing, a series of small stains/pulls and what looks like a small candle wax drip mark on the reverse, otherwise fine.
While this example certainly has its share of conditional issues, the scarcity of the item should more than make up for it. VERY, VERY hard-to-find Grande item.
