The Scream by Edvard Munch (1863-1944) is one of those paintings that everybody can recognize, as it has been replicated and parodied in so many images in popular culture, from anti-nuclear posters to emojis. BBC Arts reports on the upcoming exhibition "Edvard Munch: Love and Angst", which the British Museum will host from 11 April to 21 July, 2019.
