Original 1st printing 16&7/8 x 22&7/8" concert poster for Grand Funk Railroad appearing with the the Litter, Brian Auger & the Trinity and 4 Days and a Night at the Aragon Ballroom in Chicago, IL on 7/10/1970.
Art by Al Shamie, medium-thick glossy stock poster is in good (B) condition; there is an approximately 1" diagonal chunk out of the top left corner tip, a series of 6-7 thin vertical edge tears scattered around the outer edges (sealed on the reverse), a set of tack/pin holes, a tiny nip out of the top right corner tip, light handling, a few soft pin-prick surface stains and thin stress bends hiding within the image area, otherwise fine.
REALLY strange-looking Aragon Ballroom poster from the American Tribal Productions series.
