Original 1st printing 17&1/2 x 23" uncut printer's test proof sheet (black ink only) concert poster for the Youngbloods appearing with Portland Zoo, River and Ron Bruce at Springers Ballroom in Portland, OR on 7/18/1969.

 Art by (and SIGNED in red flair pen by) Jim Blashfield, medium-thick glossy-coated index stock poster is in very good (B/B+) condition; there is a bit of relatively minor moisture wear (slight paper warping and a light stain) along the right margin, with a few thin creases/bends, a tiny pin-prick stain and a couple of small tears in the top margin, a pair of soft diagonal bends in the upper/lower left margins, a few stray handling dings/light creases here and there and a bit of smudging on there reverse, otherwise OK.

 Pretty unique-looking one-color ARTIST-SIGNED printer's proof from the Pacific Northwest.
