Original 1st printing 15&3/4 x 21&1/4" concert poster for Van Morrison appearing with Blodwyn Pig and Blues Image at the Boston Tea Party (15 Lansdowne St location) in Boston, MA from 4/16-18/1970.

 Designer unknown, medium glossy-coated index stock poster is in good/decent (B/B-) condition; a set of tack/staple holes (all four corners), a 1" square area of tape residue in the top left corner, a moderate amount of surface wear (several bends/stress creases, pinch dings), edge/corner wear, a few stray surface scuffs and scrapes, tape pulls on the reverse, etc... this example was very likely pulled down from a public display area in 1970.

 Conditional issues aside, this is one of the less-common later period Tea Party posters and it features a great period photo of Van the Man. Here's "Come Running" from the 1970 NY Pop Festival;
