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 near mint (A-) condition; aside from a few scattered light pinch dings, this example is just about as nice as they come.

Great-looking low-run oddball psychedelic concert poster from the Nation's Capital.
