The Helen Frankenthaler Foundation in New York has donated a large abstract painting by the US post-war artist to the Tate. Vessel, the first work by Frankenthaler to enter a UK national collection, will be on show at Tate Modern in London until November 2020 alongside four paintings on loan from the foundation. Made using the signature “soak-stain” technique of pouring thinned oil paint on to an unprimed canvas placed on the floor, Vessel is one of Frankenthaler’s most significant paintings from the 1960s, according to the foundation’s director, Elizabeth Smith.
