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 near mint (A-) condition; with the exception of a nearly-invisible soft diagonal roll bend in the upper right margin, it is an absolutely  STUNNING example of this very cool-looking low-run psychedelic concert poster from the fondly-remembered Oregon ballroom. Great colors on this one!
