A photograph of Winston Churchill giving his victory salute has been airbrushed to remove his signature cigar.

In the well-known original image, Churchill makes a "V" shaped symbol with his fingers – while gripping a cigar in the corner of his mouth.

But in a reproduction of the picture, hanging over the main entrance to a London museum celebrating the wartime leader, he has been made into a non-smoker through the use of image-altering techniques.

It is unclear who is responsible for doctoring the photograph, with the museum – The Winston Churchill's Britain at War Experience – claiming not to have noticed the cigar was missing.

John Welsh, manager of the museum, admitted he was shocked to learn of the alteration, but declined to reveal who was responsible for the display and for enlarging the image.

He said: "We've got all sorts of images in the museum, some with cigars and some without. We've even got wartime adverts for cigarettes in the lift down to the air-raid shelter, so we wouldn't have asked for there to be no cigar."...
