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 index stock poster is in SUPERB mint/near mint to near mint (A/A- to A-) condition; only a stray pin-prick print hickey or two hiding within the image area and that's IT... a VERY crisp/clean example of this somewhat uncommon late-'70 Tea Party poster.
