The Manchester-born photographer Grace Robertson colourfully captured the life of women in post-war England, with her most celebrated works showing women of a certain vintage jovially drinking in pubs around London. For this image, the photographer accompanied a lively group to the Margate seaside. In a 2010 interview, Robertson said she was drawn to the women’s joie de vivre, as they “had been through two wars and a depression in the middle, [and] were incredibly exuberant” (those at the back seem less amused). An edition is held by Houston’s Museum of Fine Arts, while other images from the pub series are in the Tate’s collection. Grace Robertson, On the Caterpillar, London Women’s Pub Outing, 1956. Artist, Icon, Inspiration: Women in Photography, Phillips, New York, 7 June. Estimate $1,500-$2,500.
