Original 1st printing 16&1/2 23&1/2" Capricorn/Polydor "tour blank" promotional/concert poster for the Allman Brothers Band appearing at Knebworth Hall in Hertfordshire, England on 7/20/1974. 

 Designer unknown/not credited, medium-thin flat textured index stock poster is in excellent (B+) condition; a set of (3) horizontal and (1) vertical factory folds (as issued, item was folded into 1/6ths) with a tiny amount of wear along the fold lines and a pair of tiny holes in the intersections of the folds, a hint of handling wear (a few stray pinch bends), light surface wear and a few tiny bends hiding within the image area, otherwise fine.

 Neat little mid-'70's ABB concert poster from England, listen to the band's entire set HERE:
