Original 1st printing 28&1/4 x 15&1/2" concert poster for  Crosby, Stills, Nash & Young appearing at the Portland (OR) Coliseum on 5/5/1970.

 Art by (and SIGNED in black pen by) Richard Taylor (Rainbow Jam), medium-thick glossy-coated index stock poster is in excellent (B+) condition; there are a couple of thin diagonal bends in the lower right margin/corner, along with a few soft handling dings scattered around the outer margin area, a trace of light surface wear and a trace of moisture warping in the lower left corner, otherwise fine.

 Great-looking low-run CSNY concert poster from the Pacific Northwest.
