Guernica.
" Guernica " Pablo Picasso , 1937 oil on canvas , 349×776cm Madrid, Spain: Museo Reina Sofia One officer who considered himself culturally advanced approached the artist as he sipped his coffee at a table beneath the green pavement awning. The officer held a reproduction of the mural Guernica, barely larger than postcard size. 'Pardon me,' he said, holding the card out. 'You did this, didn't you?' Picasso put his cup delicately onto his saucer, turned to the picture and then to he officer, and responded, 'No. You did.' Dave Boling, Guernica: A Novel, Picador, 2009.
