Original 1st printing 17&1/8 x 22&1/2" concert poster for the October 1968 schedule of shows at the Matrix in San Francisco, CA. Shows listed include: Elvin Bishop on 10/8-12, Jerry Garcia (GARRCEEAH) and Friends (A/K/A "Mickey & the Hartbeats") on 10/8-10, Marvel Farm on 10/11-12, Harvey Mandel and Mad River on 10/15-17, Allmen Joy on 10/18-19, Mint Tattoo on 10/22-24, Steve Miller on 10/22-16 and Linn County on 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 is in stunning near mint (A-/B+) condition; aside from a couple of very minor handling dings and a trace of edge toning it's just about as sharp as you can ask for. Very crisp-looking Matrix poster from a very tumultuous time for the Dead; read the whole story here;
