Original 1st printing 16&7/8 x 20&3/8" concert flyer for the Chambers Brothers appearing with the South End Hate Band on 3/1/1967 and again with the Hallucinations (featuring Peter Wolf, later of the J. Geils Band) on 3/2/1967, both shows held at the Boston Tea Party (53 Berkeley Street location) in Boston, MA.

 Art by H. Weiner/Media, thick glossy-coated index stock poster is in excellent (B+) condition; there are tack/staple holes in the upper/lower right corners and in the lower left margin, along with a series of tiny pin-prick surface indentations scattered around the image area, a hint of surface scuffing and a few soft pinch dings here and there, otherwise it is an overall superb-looking example of this oddball early-'68 Tea Party poster.
