Extract from Lot Essay
“Gifted by the artist to Kenneth Tynan in 1966, the present work has remained in his family ever since. Unprecedented in Boty’s limited body of work, this collage is the only known study for a major painting and provides a tantalising insight into her working methods. Executed in the same vibrant colours as the oil painting (sold Christie’s London, 22 November 2017, lot 4), the layers of collage reveal the complexity behind this playful composition.
BUM, a splendid and mature work, was Boty’s very last painting and painted after a diagnosis for cancer that ended her life so prematurely, aged only 28 in 1966. In the face of death, it is a wonderfully vibrant piece painted in colours straight from the tube. Commissioned by Kenneth Tynan for his notorious, erotic cabaret Oh! Calcutta! it places her, to the very end, at the cutting edge of the 60s zeitgeist. The title is a play on the French ‘O, quel cul tu as’ (‘O, what an arse you have’) and in a letter to the impresario, William Donaldson, Tynan outlined a gamut of ideas for the show, one of which was ‘a pop art ballet designed by Pauline Boty, based on paintings that focus on the principal erogenous zones’. BUM, intended as the first of a series, took its cue from the punning title. Within a precisely executed proscenium arch the female bottom is exquisitely and sensuously painted, the flesh has a bloom like a peach and the work could be read as a sensuous celebration of life. Yet the meaning is surely more ambiguous. We have a reified body part, set above the demotic title, BUM, rawly proclaimed in chunky san-serif lettering and revealed ‘on stage’ inviting perhaps a slap or a caning as much as a caress. Certainly, any simple celebration of sexual pleasure has been superseded by something more complex and interesting.
We are very grateful to Dr Sue Tate, author of Pauline Boty: Pop Artist and Woman, Wolverhampton, 2013, for preparing this catalogue entry.”
