Original 1st printing 17&7/8 x 24" concert poster for psych-rock legends Iron Butterfly appearing with Savoy Brown and Catfish (Hodge) at the Spectrum in Philadelphia, PA on 2/14/1970.

 Artist unknown/not credited, thick cardboard stock poster is in good to very good (B to B/B+) condition; a set of tack/nail holes (all four corners, a 2" diagonal bend in the top left corner, scattered handling /fingerprint marks, a few stray surface scuffs, a hint of toning and a slight warp/wave to the board, otherwise fine.

 AWESOME-looking low-run cardboard concert poster from Philly with a great design.
