Original 1st printing 16 x 22&5/8" concert poster for the Chambers Brothers appearing with the Buddy Miles Express and Buffalo Springfield (Dewey Martin edition- no Richie/Neil/Steve/Bruce) at the Portland (OR) Memorial Coliseum on 12/22/1968.

 Designer unknown/not credited, thick cardboard stock poster is in good to very good (B to B/B+) condition; there are a series of semi-pronounced thin creases/stress bends traversing the "Chambers Brothers" lettering, across the bottom of the photo and the lower margin area, along with a couple of tiny corner-tip creases and a stray pressure crease or two scattered around the outer margin area, otherwise fine.

 This version of Buffalo Springfield had only Dewey Martin (drums/vocals) from the original band, along with several mostly-unknown musicians (although trumpeter Jim Price eventually went onto bigger things with Joe Cocker, the Rolling Stones and MANY more)... very curious BS-related concert artifact from the end of 1968 with a great psychedelic design.
