Original 1st printing 8&1/2 x 10&1/2" double-sided concert/event flyer for Pink Floyd appearing with the Steve Miller Band, Captain Beefheart and the Magic Band, Roy Harper, Graham Chapman and Friends from Monty Python, Linda Lewis and D.J. John Peel at Knebworth Park in Stevenage, (Hertfordshire) England on 7/5/1975.
Design/concept by Freddy Bannister, medium-thin flat stock flyer is in good to very good (B to B/B+) condition; a set of tack holes (all four corners), light handling/edge wear, a few stray thin bends and a series of tiny pin-prick age spots scattered around the image area, otherwise fine.
A classic mid-'70's UK festival artifact from the second edition of the semi-annual event. Check out a decent-sounding audience recording of Captain Beefheart's FULL set HERE:
