Original 1st printing 10&5/8 x 17" concert poster for the Charlie Musselwhite Blues Band appearing with Listening at the Boston Tea Party (53 Berkeley Street location) in Boston, MA from 12/26-28/1968.

 Artist unknown/not credited (likely Bob Driscoll) medium flat index stock poster is in excellent (B+) condition; there is a thin diagonal bend (about 3" long) in the bottom center margin, along with a few tiny edge dings scattered around the image area, a pair of tiny pressure creases in the upper left/right corner tips, a soft handling ding/pin-prick surface scuff or two hiding within the image area and a soft smudge mark on the reverse, otherwise fine.

 Pretty sharp-looking semi-used example of this somewhat hard-to-find Berkeley Street BTP poster, this is actually the first example I have come across.
