Original 1st printing 12&3/8 x 20" concert poster for Blues Interchange appearing with Papa Bear's Medicine Show at the Retinal Circus in Vancouver, BC, Canada from 11/17-18/1967.

 Art by Fisher, medium-thick glossy-coated index stock poster is in near mint (A-) condition; other than a whisper of surface wear, a tiny bump in the top right corner tip and a stray fingerprint smudge or two hiding within the image area, it is a VERY sharp/clean example of this eye-searing psychedelic concert poster from the Retinal Circus.
