Original 1st printing 20&1/2 x 28&3/4" concert poster for Spirit appearing with Mason Proffit(t) and Sugarloaf at the Fairgrounds Coliseum in Salt Lake City, UT on 3/13/1971.

 Design by Stan Shubach (for Rainbow Jam), medium-thick glossy-coated index stock poster is in near mint to excellent (A- to A-/B+) condition; aside from a couple of VERY well-camouflaged stray pinch/handling dings and tiny surface scratches hiding within the image area and a couple of tiny pressure creases/bumps in the corner tips, this example is pretty much as clean/sharp as they come.

 FANTASTIC-looking cosmically-themed low-run concert poster from the Rainbow Jam series.
