Original 1st printing 6 x 9&7/8" concert handbill for the Grateful Dead appearing with Quicksilver Messenger Service at the Eureka (CA) Municipal Auditorium on 1/20/1968.
Art by George Hunter, similar images (Portland/Seattle) are featured in the Art of Rock book on page 287.
Medium flat index stock handbill is in decent/used (B/B- to B-) condition; a series of tack/pin holes in the top center margin, edge wear, a series of horizontal bends, toning, a large coffee stain in the lower left quadrant, pencil/pen scratch on the reverse and a series of surface marks... definitely a used (but still very charming) example of this VERY hard-to-find version of the "NOTICE!" handbill.
There is actually a very sharp-sounding Charlie Miller transfer of the show, check it out HERE:
