Original 1st printing 14&1/8 x 20" concert poster for the Paul Butterfield Blues Band appearing with Mosaic Virus at the Ambassador Theatre in Washington DC from 10/13-15/1967.

 Art by Chrysanthemum Graphics, medium-thin glossy stock poster is in excellent (B+) condition; aside from a couple of hairline-thin diagonal bends in the upper left corner/margin and a few scattered pinch creases here and there, this example is just about as sharp as they come.

AWESOME-looking low-run oddball psychedelic concert poster from the short-lived Washington DC psychedelic venue.
