Original 1st printing 11&3/4 x 22&3/4" concert poster for the Grateful Dead appearing with A.B. Skhy, Wildwood, Country Weather and Commander Cody at Cal Expo in Sacramento, CA on 11/21/1969 (*KZAP-FM 1st Birthday Party) 

 Designer unknown/not credited, medium-thick flat index stock poster is in good to very good (B to B/B+) condition; there are tack/staple holes in all four corners and in the top center margin, along with a series of semi-pronounced vertical stress bends hiding within the image area, a soft discoloration/stain in the lower right corner, a slight vertical curl to the paper, a couple of fairly minor edge creases, a set of small light tape pulls on the reverse and the image is printed VERY slightly off-register (uneven borders), otherwise fine... none of the conditional issues are too invasive, and the poster still presents itself nicely.

VERY, VERY hard-to-find late-'69 Grateful Dead poster from Northern California, I haven't seen this one in almost 20 years. Check out the second set of the show HERE:
