Original 1st printing 16&1/2 x 22&1/8" concert poster for the Grateful Dead appearing with New Riders of the Purple Sage at Winterland in San Francisco, CA on 10/9/1972 (*road crew benefit)

 Art by "TH", image is featured in the Art of Rock on page 348 (plate 4.51).

 Medium-thick glossy stock poster is in decent (B/B-) condition; there are tack holes in all four corners with a bit of tattering in the top left/right corners, along with a moderate amount of edge creasing/wear, a large thin horizontal/diagonal bend traversing the upper part of the image area, a series of handling dings/tiny stress creases throughout, a light toning and a few large pieces of clear packing tape on the reverse... a bit on the used side, but it's all there and it is the first one I have come across in 25+ years.

 Despite it being a somewhat crudely-rendered piece, this is definitely one of the harder-to-find early-'70's Dead posters from Winterland- I don't think they printed a lot of these. Check out the show (featuring a guest appearance by a rather lively Grace Slick) HERE:
