Critics have praised one of the largest collections of Henri Matisse's "cut-out" artworks ever assembled, for an exhibition opening at Tate Modern.
The French artist cut out paper shapes for collages when ill-health prevented him from painting, producing famous pieces such as The Snail and Blue Nude.
He worked from a wheelchair after treatment for cancer and the exhibition compiles work dating from 1937 to 1954, when he died aged 84 of a heart attack.
