Original 1st printing 14 x 19&1/2" concert poster for Grand Funk Railroad appearing at the Field House on the campus of the University of Oklahoma in Oklahoma City, OK on 9/3/1970.

 Artist unknown/not credited, thick glossy stock poster is in good (B) condition; there are a set of tack holes (all four corners), a hard 6-7" horizontal bend/crack traversing the ticket outlet area in the lower left, a moderate amount of surface wear/scuffing, a slight curl to the paper, a few small pinch dings/tiny bends here and there and a whisper of toning/subtle moisture staining, otherwise fine.

 VERY early (1970) low-run regional Grand Funk Railroad poster, this example has also been HAND-SIGNED (in black sharpie) by Grand Funk lead singer/guitarist Mark Farner.
