A menu signed by the WWII Dambusters from a 1943 dinner celebrating their decoration has sold for £4,465.
The Dam Busters dinner menu was signed by 31 crew members
Also for sale at Bonham's auctioneers in Oxford was a cap worn by their leader, Air Marshal Sir Arthur "Bomber" Harris, which sold for £3,055.
Under his command, the Dambusters raided the Ruhr Valley dams causing massive flood damage.
Both auction items were sold to private collectors, surpassing their estimated prices and delighting auctioneers.
Bonhams' arms and militaria specialist Tony Cribb said: "I'm absolutely delighted with how well the Bomber Harris cap and Dambusters menu did."
Bomber Harris' side cap was also accompanied by a letter from him, thought to be addressed to an admirer.
The cap and letter from Sir Arthur Harris, Marshal of the Air Force
"I cannot imagine why anybody should require a personal souvenir from me," the letter reads.
"I enclose a cap for which I have no further use! Worn by me during the 1939/45 War Arthur T Harris M. RAF."
The menu features 31 signatures of the Dambusters crew and others, collected at a dinner in their honour in London.
They were collected by Flight Lieutenant Richard Algernon Dacre Trevor-Roper, a tail-gunner killed in action in March 1944.
Other items on sale included a dockyard drawing of Adolf Hitler's yacht, Aviso "Grille", which sold for £795.
