Original 1st printing 23 x 17&1/2" concert poster for Iron Butterfly appearing with Country Joe & the Fish at Merriweather Post Pavilion in Columbia, MD on 8/24/1968.

 Design by McNeill, the image is featured in the Art of Rock book on page 304 (plate 3.159). Medium thin flat index stock poster is in absolutely fantastic mint/near mint to near mint (A/A- to A-) condition; short of the odd stray corner/edge/handling ding, a cleaner example would be hard to find.

 Really nice-looking regional oddball poster from the AOR in GREAT shape.
