Original 1st printing 20 x 15&1/4" concert poster for UK skiffle-rockers Mungo Jerry appearing with Humble Pie (featuring Steve Marriott and Peter Frampton) and Spider John Koerner at the Boston Tea Party (15 Lansdowne St location) in Boston, MA from 10/8-10/1970.

 Design by Ravioli Grafitti Studios (Bob Goldman), medium-thick flat vellum stock poster is in good (B) condition; there are pin/tack holes and tiny creases in each of the four corners, a few thin vertical creases running down the right margin, a series of soft bends/thin creases hiding within the image area, a few tiny edge tears a thin vertical roll bend/soft crease running along the left side of the photo (up to the top left margin) and a hint of surface wear, otherwise fine.

 Very decent-looking (if slightly used) example of this unusual-looking late-'70 Tea Party poster.
