Original 1st printing 13&5/8 x 22" concert poster for "A Party for Mother Earth", a show featuring appearances by the New Riders of the Purple Sage, Country Joe McDonald, Ace of Cups, Stoneground and Grootna, held  at Friends and Relations Hall (former Family Dog on the Great Highway location) in San Francisco, CA on 6/3/1971.
 
  Art by Alton Kelley, image is featured in the Art of Rock book on page 335 (plate 4.11).
 
 Medium glossy-coated index stock poster is in very good to excellent (B/B+ to B+) condition; there are staple holes and tiny indentation dents in all four corners, a single tack hole in the bottom center margin, a series of VERY light pin-prick age spots in the lower portion of the image area, a few light surface scratches/soft handling dings/fingerprint smudges and a  tiny indentation/hole just beneath the "r" of "For", otherwise fine.
 

 Neat little early-'70's Kelley one-off benefit concert poster from the post-Family Dog Great Highway.
