• Two versions of Vincent van Gogh’s iconic Sunflowers have been reunited for the first time in 65 years in London at the National Gallery. The two paintings – one from the National Gallery and the other from the Van Gogh Museum in Amsterdam – come from a five-painting series the artist created in 1888 while staying in Arles. They were apparently painted while he was waiting for his friend Paul Gaugain to arrive and were to decorate the bedroom Gaugain would stay in as gift to him. The free display in Room 46 of the Trafalgar Square Gallery and will be shown until 27th April. Meanwhile, the gallery is celebrating the donation of another van Gogh – Head of a Peasant Woman, the first early work by the artist to enter its collection. It is one of a series of around 40 portraits of the peasants of the village of Nuenen, in The Netherlands, which were painted in late 1884/early 1885. For more, see www.nationalgallery.org.uk.
