Guernica is a painting by Pablo Picasso, depicting the bombing of Guernica, Basque Country, by German and Italian warplanes at the behest of the Spanish Nationalist forces, on April 26, 1937, during the Spanish Civil War.
Guernica shows the tragedies of war and the suffering it inflicts upon individuals, particularly innocent civilians. This work has gained a monumental status, becoming a perpetual reminder of the tragedies of war, an anti-war symbol, and an embodiment of peace.
A tapestry copy of Picasso's Guernica is displayed on the wall of the United Nations building in New York City, at the entrance to the Security Council room. Commissioned in 1955 by Nelson Rockefeller, and placed on loan to the United Nations by the Rockefeller estate in 1985, the tapestry is less monochromatic than the original, and uses several shades of brown.
On February 5, 2003 a large blue curtain was placed to cover this work, so that it would not be visible in the background when Colin Powell and John Negroponte gave press conferences at the United Nations.
On the following day, it was claimed that the curtain was placed there at the request of television news crews, who had complained that the wild lines and screaming figures made for a bad backdrop, and that a horse's hindquarters appeared just above the faces of any speakers.
Some diplomats, however, in talks with journalists claimed that the Bush Administration pressured UN officials to cover the tapestry, rather than have it in the background while Powell or other U.S. diplomats argued for war on Iraq.
