The work "Churchill" made him famous in one fell swoop. It is said that there is a story in it. For Churchill, a strong-armed politician during World War II, Cash wanted to embody Churchill’s lion-like toughness. But Churchill did not listen to the photographer's instructions like an actor, but looked very leisurely with a cigar in his mouth. In order to anger Churchill, Cash suddenly stepped forward and snatched the cigar from Churchill's mouth when Churchill was not paying attention. Churchill suddenly became angry, and Cash took the opportunity. Press the shutter and take this famous photo.
