Original 1st printing 11 x 14&7/8" "tour blank" concert poster for Quicksilver Messenger Service.
Designer unknown/not credited, image (filled in with information from the 4/30/1966 (BG 4) show at the Fillmore Auditorium) is featured in the Art of Rock book on page 145 (plate 2.45). (*This is an unused/no-info blank)
Thick flat index stock poster is in good to very good (B to B/B+) condition; there are a trio of small surface stains (tape residue and a small drip mark) in the upper margin area and in the left/right corners (each about 1/2"), a couple of thin edge creases, a tiny stress bend/pinch ding or two hiding within the image area, a touch of toning, a few light surface scuffs and a few ultra-tiny edge/corner dings, otherwise fine.
VERY uncommon Quicksilver item from the earliest days of the the band's existence.
