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 BEAUTIFUL near mint (A-) condition; aside from a few nearly-invisible handling dings here and there, an ultra-thin stress crease just above the "J" of "Jerry" and a tiny corner-tip bump or two, it is an ULTRA-SHARP example of this semi-uncommon late-period Tea Party poster.
