With an 8in tear to the bottom left edge and some small nicks and holes around the edges, the 2ft 6in x 3ft 4in (76cm x 1.02m) poster sold for £1800 against a guide of £600-1000 in the Special Auction Services (20% buyer’s premium) Music & Entertainment sale on February 16.

Although offered in the SAS Newbury saleroom, the poster was consigned through the SAS Dudley branch recently established after Aston’s closed.

Thomas Forrester of SAS said: “A local lady from Cannock had found them in a relative’s property years ago and forgotten she even had them until last year when she and her son decided to clear out the garage where they had been put, rolled up, for over 10 years.”
