Britain at War

The catalogue Britain at War was published to accompany the exhibition. Withdrawal from Dunkirk features on the dust jacket and as a frontispiece. It was used on the poster too.

"Britain at War was the Committee's major overseas exhibition with oils and watercolours from over thirty artists. It opened at the Museum of Modern Art, New York, in May 1941, with some 3,000 people attending on the opening day. The selection of works was aimed at undermining American neutrality. The exhibition went on to Baltimore before fourteen images, with Canadian themes, were added for showings in Ottawa, Toronto and Montreal. The exhibition was then split in two for display in Pittsburgh and London, Ontario before the entire catalogue was exhibited in San Francisco in 1942. Britain at War then toured Central and South America in place of 111 WAAC paintings that had been lost when the ship taking them to Rio de Janeiro was sunk."
