Original 1st printing 20&3/8 x 28" event poster for the Hog Farm hosting a series of Thursday night "Open Celebrations" at Cinemateque 16 in Los Angeles, CA, circa late 1967-early 1968.
 
 Art by (and SIGNED in gold paint pen by) Rick Griffin, image (2nd printing 1976 European Edition with "Bindweed Venom" in place of "Cream Pudding") is featured in the Art of Rock book on page 238 (plate 2.358).
 
 Thin glossy stock poster is in used (B-) condition; there is a small wedge of paper (appx. 3/4" square) missing from the top right corner tip, along with a small 3/4" vertical tear in the lower left margin/corner, a bit of minor edge wear/light creasing and a tiny nip tear or two scattered around the outer margin area, a series of VERY thin horizontal roll bends along the left margin, a few well-camouflaged handling/stress creases hiding within the image area and a couple of light tape pulls on the reverse side, otherwise OK.
 
A very presentable (if a bit used) ARTIST-SIGNED example of this semi-hard-to-find late-'60's Griffin classic.
