For readers who are new to this series, let me repeat my explanation of the title. In Volume V of Martin Gilbert’s monumental biography of Churchill (Winston S. Churchill:The Prophet of Truth: 1922-1939), we learn that an enormous poster appeared in the Strand and at other prominent points around London in the last week of July 1939. Placed by an advertising agent who was anxious “to get people thinking of the reinstatement of Churchill,” the poster asked simply: “What price Churchill?” (A photograph of the poster can be seen here.) On July 25, 1939, the Daily Mirror noted: “The writing on the wall? This giant poster is causing considerable comment.”
