Original 1st printing 14&1/8 x 22&5/8" concert poster for the one and only Isaac Hayes (and 24-Piece Orchestra) appearing with Luther Ingram, the Bar-Kays and Mad-Lads at the Spectrum in Philadelphia, PA on 3/31/1971.

 Designer/photographer unknown/not credited, medium-thick glossy-coated index stock poster (printed with reflective silver ink) is in excellent (B+) condition; there is a 1/2" tear in the top center margin (going through the "d" of "Woods"), along with a couple of thin horizontal hairline creases/bends going across the top margin, a couple of tiny corner-tip pressure creases and a thin surface scratch/soft handling ding or two hiding within the image area, otherwise it is a KILLER example of this early-'70's concert poster for the inimitable "Mr. Hot Buttered Soul".
