I didn’t think that the Hauser & Wirth exhibition of Picasso and Louise Bourgeois would be open today, as it’s a bank holiday, but it is: a beautiful set of juxtapositions on the themes of sex, carnality, marriage and desire. No photography, of course, because so much comes from private collections, including wonderful Picasso drawings and a rich group of Louise Bourgeois sculptures, massed in grand glass display cabinets. The best juxtaposition is a Picasso puppet (1935) and one by, or belonging to, Bourgeois (1982). Bourgeois totally lives up to the juxtaposition of fecund form.
