Original 1st printing 14 x 22" cardboard tour blank concert poster (with printed show information) for Flint, MI hard-rock superstars Grand Funk Railroad appearing at Duluth (MN) Arena on 10/21/1973.

 Designer unknown (photos by Lynn Goldsmith), medium-thick cardboard stock poster is in good (B) condition; there are a decent-sized pair of pronounced diagonal/horizontal bends in the upper right quadrant/corner, a pair of small drag pull holes in the top left/right corners, a 3/4" diagonal pull in the bottom right corner tip, a few stray surface scuffs and thin surface scratches, a hint of edge wear and a small tape pull on the reverse, otherwise fine.

 Neat-looking early-'70s cardboard Grand Funk poster from the "We're An American Band" period with great photos of the band in action. Additionally, this example has been HAND-SIGNED (in black sharpie) by lead singer/guitarist Mark Farner (at B.B. King's in NYC in 2007).
