A beautiful Near Mint first printing of the poster for Bo Diddley and Big Brother & The Holding Company at the Avalon Ballroom known as FD 21, or "Earthquake." This rare classic by Alton Kelley & Stanley Mouse is reproduced in The Art Of Rock.(br)This is in superb condition; there are 3 small tape stains/pulls on the reverse, none visible on the front. Each is approximately 1/2" . Expert restorer Chris Fennell has removed two very small tape stains on the front edges, and none of the restoration is at all visible (you would never know, but we always note any restoration.) There is a tiny bit of red ink missing in the top right border–it's smaller than the size of a match head and we didn't notice it until just now–it would be very easy to fix if you wish. Otherwise this is in mint condition.(br)The new 7th Edition of Fred Williams "Rock Poster Price Guide" lists this as being worth $1350. to $1800. A great poster, in beautiful condition.
