Original 1st printing 22 x 8&1/2" concert poster for country-blues duo Spider John Koerner & Willie Murphy appearing with Eric Mercury at the Boston Tea Party (15 Lansdowne St location) in Boston, MA from 2/19-21/1970.

 Design by Bob Driscoll (not credited), medium-thick flat index stock poster is in SUPERB near mint (A- to A-/B+) condition; a soft pinch ding and thin soft vertical scuff mark in the left margin (just below "tickets"), a couple of tiny corner bumps, a whisper of edge toning and a stray pin-prick ding or two hiding within the image area, otherwise fine.

 Great-looking example of this somewhat uncommon early-'70 Tea Party poster.
