Royal Mail have released six special stamps to mark the 75th anniversary of the Battle of Britain.
The six stamps feature photographs from during the Battle of Britain, between the summer and autumn of 1940.
One showcases the Battle of Britain flight command bunker in Stanmore, the main fighter command headquarters during the war.
The Operations Room, in Bentley Priory, is part of a Grade II-listed country house, and is open to the public.
The stamp collection features iconic scenes from the heroic 112-day battle of 1940.
Tragically, before the RAF finally defeated the Luftwaffe, only around half of the estimated crew of 3,000 survived.
More than 3,000 aircraft were downed – 1,023 from the British side and 1,887 of the Luftwaffe.
Stamp strategy manager at Royal Mail, Philip Parker, said: “All images were taken between July and September 1940 and that limited the choice because they were obviously difficult to find because taking pictures and naming them wasn't something they did.
“That image is from the Imperial War Museum with help from RAF Hendon curators.
“It's completely authentic, we wanted to show not just a pilot but all of the crew such as armourers and engineers.
“While we don't have a specific date for the picture we know it was taken at the height of the battle of Britain.
“The idea behind the stamps was to commemorate not just the few but the many who contributed to the war effort.
“To my understanding the stamps have gone down very well.”
The stamps are currently on sale and can be purchased from your local Royal Mail office, at the Royal Mail website or by calling 03457 641 641.
