Original 1st printing 17 x 22" concert poster for Mountain appearing with Brethren and Skid Row (featuring Gary Moore) at the Boston Tea Party (15 Lansdowne St location) in Boston, MA from 11/27-28/1970.

 Design by Eric Engstrom, medium-thick flat index stock poster is in very good (B/B+) condition; there are a few light roll creases traversing the image area, along with a pair of hairline-thin diagonal bend (about 6") going through "Mountain", a couple of VERY light handling dings/stress bends and tiny pin-prick surface spots hiding within the image area and a 3/4" edge tear in the upper right margin, otherwise fine. 

 Most of the conditional issues are extremely well-camouflaged within the design, it presents itself quite nicely. KILLER late-period Boston Tea Party poster, this example was owned by Gary Moore's manager.
