“The world’s largest signed Pablo Picasso canvas, which has not been seen in public for 20 years, was unveiled in London on Tuesday. A 10-metre high reproduction of his work Deux Femmes Courant Sur La Plage is on show at the Royal Opera House. The painting was copied from the original in 1924 by a scene painter for use as a stage curtain in a ballet. It will go on permanent display at London’s Theatre Museum as part of a £12m redevelopment.”
