Original 1st printing 17&1/2 x 22&5/8" uncut pair of concert posters for the Youngbloods appearing with Seals & Crofts and Livingston Taylor at the Boston Tea Party (15 Lansdowne Street location) in Boston, MA from 3/19-21/1970.

 Artist unknown/not credited, medium-thick flat index stock poster is in very good to excellent (B/B+ to B+) condition; tiny staple holes (all four corners), a 1/2" tear in the bottom center margin, a couple of small areas of toning and a few minor creases along the top edge and a few light/soft surface scuffs scattered around the image area, otherwise fine.

 REALLY unusual-looking original Tea Party proof sheet from early 1970.
