advance of extensive renovations at UN Headquarters. The Guernica tapestry was the showcase piece for the grand reopening of the Whitechapel Gallery. It was located in the 'Guernica room' which was originally part of the old Whitechapel Library. In 2012 the tapestry was on loan from the Rockefeller family to the San Antonio Museum of Art in San Antonio, Texas. It was returned to the UN by March 2015. Nelson A. Rockefeller Jr., the owner of the tapestry, took it back in February 2021. In February 2022, it was returned to the wall outside the UN Security Council. Significance and legacy During the 1970s, Guernica was a symbol for Spaniards of both the end of the Franco regime following Franco's death and of Basque nationalism. The Basque left has repeatedly used imagery from the picture. An example is the organization Etxerat, which uses a reversed image of the lamp as its symbol. Guernica has since become a universal and powerful symbol warning humanity against the suffering and devastation of war. There are no obvious references to the specific attack, making its message universal and timeless. Art historian and curator W. J. H. B. Sandberg argued in Daedalus in 1960 that Picasso pioneered a “new language” combining expressionistic and cubist techniques in Guernica. Sandberg wrote that Guernica conveyed an “expressionistic message” in its focus on the inhumanity of the air raid, while using "the language of cubism". For Sandberg, the work's defining cubist features included its use of diagonals, which rendered the painting's setting "ambiguous, unreal, inside and outside at the same time". In 2016, the British art critic Jonathan Jones called the painting a "Cubist apocalypse" and stated that Picasso "was trying to show the truth so viscerally and permanently that it could outstare the daily lies of the age of dictators". Works inspired by Guernica include Faith Ringgold's 1967 painting The American People Series #20: Die; Goshka Macuga's The Nature of the Beast (2009–2010), which used the Whitechapel-hosted United Nations Guernica tapestry; The Keiskamma Guernicas (2010–2017); and Erica Luckert's theatrical production of Guernica (2011–2012). Art and design historian Dr Nicola Ashmore curated an exhibition, Guernica Remakings, at the University of Brighton galleries from 29 July 2017 to 23 August 2017.
