In 1937, the most famous artist in the world – a Spaniard from Málaga — made a mural sized painting depicting the recent destruction of Guernica by German Luftwaffe bombers. The painting was controversial. The Communists thought it too abstract; they wanted socialist realism. The liberals thought it was too political; they wanted beauty. The fascists and Nazis thought it was degenerate; they wanted it burned. But following its initial exhibition at the Spanish pavilion of the Paris World’s Fair of 1937, the picture’s stature and renown grew.
