Original 1st printing 22 x 15&1/2" concert poster for the Grateful Dead appearing at Irvine Meadows Amphitheater in Irvine, CA on 3/27/1983.

 Art by "Hi-De-Ho 1", medium-thick flat index stock poster (most-likely fan-generated and sold in the lot at the show) is in fantastic near mint (A- to A-/B+) condition; there are a series of handling dings scattered around the outer margin area, along with a stray surface smudge/tiny stress bend or two and a hint of surface dirt, otherwise it is a GREAT-looking example of this uncommon early-'80's GD lot poster.
