Original 1st printing 17&/2 x 22&3/8" double-sided untrimmed printer's test proof sheet for Chicago appearing with River at Springer's Ballroom outside of Portland, OR on 3/15/1970 backed with a single-color (orange) proof for the Animals* appearing with Outer Edge and the Seeds at D Street in Portland on 3/19/1970. *a fake/imposter band that was using the original band's name

 Design by Michael James Strickland (Chicago) and Ron Barzee (Animals), medium-thick flat index stock proof is in excellent (B+) condition; there is a bit of mild creasing and a few thin bends stretching along the lower right margin, along with a few thin handling/stress bends here and there, a hint of edge/corner-tip creasing and a bit of either toning or ink spread on the Animals side, otherwise fine.

Very unique (and ultra-psychedelic) early 1970's PNW concert artifact.
