Original 1st printing 23&1/2 x 29" concert poster for Jefferson Airplane and Iron Butterfly appearing together at Aaron Russo's Electric Theatre (shortly before the venue was renamed the Kinetic Playground) in Chicago, IL on 7/24/1968. 

 Artist unknown, medium glossy stock poster is in excellent (B+) condition; there are a couple of semi-soft horizontal folds (poster was rolled up and flattened at one point), a thin 3" diagonal bend in the lower left corner, a stray edge/corner crease or two, ultra-light surface wear and a few small handling/stress bends hiding within the image area, otherwise fine.

 VERY cool (and hard-to-find) low-run regional Airplane piece from Aaron Russo's legendary Chicago nightspot. Check out this GREAT list of shows held at the venue HERE:
