Original 1st printing 17&1/8 x 22&3/8" concert poster for the October 1968 schedule of shows held at the Matrix in San Francisco, CA. Shows listed include: Elvin Bishop from 10/8-12, Jerry Garcia (GARRCEEAH) and Friends (A/K/A "Mickey & the Hartbeats") from 10/8-10, "Marvel" (Marble) Farm from 10/11-12, Harvey Mandel and Mad River from 10/15-17, Allmen Joy from 10/18-19, Mint Tattoo from 10/22-24, Steve Miller from 10/22-16 and Linn County from 10/25-27. 

 Art by George Chacona and Marty Rice, image is featured in the Art of Rock on page 166 (plate 2.118).

 Medium flat vellum stock poster is in decent (B/B-) condition; there is moderate degree of toning/subtle ink fading, along with a series of creases/thin bends scattered around the outer margin area, a moderate amount of handling wear, a series of tack/nail holes in the "re" of "Fillmore" and in the top center margin, a few stray thin stress creases here and there, corner-tip bends and nine (9) small tape shadows and a bit of pen scratch on the reverse side... this example has clearly been "around the block" a few times, but it's still all there!

 Very cool-looking Rick Griffin-influenced concert poster from the Matrix. Stream the 10/8 show HERE:
