It has been revealed that a clumsy visitor to the Tate Modern in London caused significant damage to a Joan Miró masterpiece that was on loan from the Fundació Joan Miró in Barcelona. The incident occurred on 7 July 2011 when the visitor stumbled and used both hands to steady himself against the painting, causing marking and dents on the painting’s surface. The visitor alerted the Tate Modern immediately, prompting them to conduct emergency conservation repairs. The cost of the repairs and the depreciation in the painting’s value was £203,000 ($326,000).
