Original 1st printing 7 x 10" concert flyer for the Grateful Dead with Palace Meat Market at Springer's Ballroom outside of Portland, OR on 5/30/1969 and at the University of Oregon's Macarthur Court on 5/31/1969. Artist unknown (photo by Thomas Weir), thin flat pulpy index stock flyer is in superb near mint (A-) condition; the only issues are a slightly off-register photo and a small printing glitch below the map in the lower left corner, otherwise it's a fine-looking example of this semi-uncommon Grateful Dead image; check out a very decent-sounding (for 1969) recording of the gig (complete with a "Yellow Dog Story") HERE:
