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 black 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 very good to excellent (B/B+ to B+) condition; there are a series of small nicks, thin crinkle creases and tiny edge tears (none larger than 3/4") scattered around the outer margin area, a few stray handling creases and tiny stress bends here and there, a small amount of ink smear on Rick's signature and a whisper of surface wear, but overall it is one of the best-looking examples I have come across.
The original 1960's-era 1st printing of this poster is VERY hard to find, especially in decent shape. The fragility of the stock tends to accept damage very easily, fortunately this example seems to have been spared most of the usual wear and tear associated with these posters.
An absolutely GORGEOUS ARTIST-SIGNED example of this hard-to-find Griffin classic.
