Original 1st printing 14 x 11&1/8" silkscreen concert poster for the Butterfield Blues Band (with Michael Bloomfield) appearing with Bola Sete at Freeborn Hall on the campus of the University of California in Davis on 1/29/1967. 

 Artist unknown/not credited, thick cardboard stock hand-pulled silkscreen poster is in excellent (B+) condition; there are a few VERY well-hidden staple/pin holes in hiding the top center margin, in all four corner tips and along the left margin, along with a couple of VERY light surface spots/dings, tiny stress bends and light surface scratches hiding within the image area and a few tiny water droplet marks/ink streaks on the reverse side, otherwise it is an absolutely GORGEOUS example of this VERY scarce/uncommon early-'67 silkscreen oddball from UCD.

 Presumably only a few examples were printed and were most likely posted exclusively on campus.
