Original 1st printing 14 x 21&3/4" concert poster for Country Joe & the Fish appearing with Notary Sojac at Springer's Ballroom outside of Portland, OR on 12/12/1969.

 Art by Jim Blashfield, medium-thick flat index stock poster is in GORGEOUS mint/near mint to near mint (A/A- to A-) condition; with the exception of a nearly-invisible soft pinch ding or two hiding within the image area, it is a STUNNING example of this very cool-looking low-run psychedelic concert poster from the fondly-remembered Oregon ballroom.
