While the original 'Guernica' is a painting by Picasso, a famous tapestry version of the work has its own unique history. Commissioned by Nelson Rockefeller in 1955 after Picasso refused to sell him the original, the tapestry was woven in France under Picasso's supervision. In 1985, the Rockefeller family loaned it to the United Nations, where it hung outside the Security Council chamber for decades as a reminder of the human cost of war. A famous moment of controversy occurred in 2003, when the tapestry was covered with a blue curtain during a press conference by Colin Powell regarding the Iraq War. Officials claimed it was to provide a better backdrop for television, but critics argued it was to hide the powerful anti-war imagery. The tapestry was briefly removed in 2021 for conservation but was returned to its prominent position at the UN in 2022, continuing to serve as a silent witness to international diplomacy.
