Original 1st (Tea Lautrec credit at bottom) printing 20&1/8 x 28" (top edge trimmed appx. 1/2") concert tour poster for the Who and the Grateful Dead appearing together at Oakland Stadium on 10/9-10/1976.
Art by Phil Garris, image is featured in the Art of Rock on page 345 (plate 4.43) and is part of Bill Graham's "Day on the Green" series.
Medium-thick glossy-coated index stock poster is in good/decent (B/B- to B-) condition; aside from the aforementioned edge trimming along the top edge, there are a series of tiny edge nicks and dings, a few stray pinch marks/fingerprints and a few light surface scratches (most are well-hidden within the design), otherwise fine.
Nice-looking mid-'70's BGP poster from a HUGE 1976 show. Check out the 10/9 Grateful Dead set HERE:
