Original 1st printing 8&3/8 x 10&7/8" 20-page concert program for the Grateful Dead appearing at the Yale Bowl in New Haven, CT on 7/31/1971. Program has a glossy-coated index stock cover and thin flat index stock pages and is in very good to excellent (B/B+ to B+) condition; a light to moderate degree of moisture wear (warping on the outer cover and a bit of minor rippling on a few of the interior pages), along with a scuff/surface dings on the outer cover, but the program is completely intact- no missing pages, doodles or the usual amount of inspired embellishment usually associated with items from this era. SUPER-uncommon regional single-show Dead program from a somewhat notorious show... you can read all about what happened in the comments section on the Archive (and listen to the show as well):
