Original 1st printing 6 x 9" blank-reverse concert handbill for Iron Butterfly appearing with the Music Box at the Masonic Temple in Portland, OR on 6/29/1968. *also advertises Echoes and Sound Vendor at the "Avalon Ballroom" in PDX on 6/28

 Artist unknown/not credited, medium-thick flat stock handbill is in very good to excellent (B/B+ to B+) condition; there is a bit of handling wear and a subtle moisture wave to the paper, along with a couple of tiny corner-tip/edge dings and a whisper of light surface dirt, otherwise fine.

 Unusual mid-'68 Iron Butterfly concert artifact from Portland, I believe this is the first time I have offered it up.
