Here is Herbert Mason's iconic shot of St. Paul's Cathedral (previously blogged here) as it appeared in the Daily Mail on 30 December 1940. Mason captured this shot from the rooftop of the Daily Maily building during the German firebombing of the City of London 29 December 1940. The paper's headline says: "War's Greatest Picture: St. Paul's stands unharmed in the midst of the burning City."
