She was determined to pursue a career in art, despite her father’s insistence that she study law, and this 1942 painting of fish and a lemon on a kitchen counter shows the extraordinary talent and avant-garde sensibility of an artist who was then only 20 years old — and had not yet met Picasso, with whom she would have two children Price on request Private Sales | | | These Van Cleef & Arpels leaf brooches are brilliant examples of the jeweller’s ‘mystery-set’ technique, developed in the 1930s. The pieces are ingeniously designed so that the gems — round and calibré-cut diamonds and calibré-cut rubies — are displayed without a visible metal setting. The overall effect, with gold trim only appearing around the edges and on the stem of each leaf, is dazzling Price on request Private Sales | | | Dating from around 1770, this George III mahogany bookcase is inscribed ‘I.W. Crompton, Birmingham’ in several places. It is an imposing piece of furniture, from the fluted cornice at the top to the panelled cupboards below. There are glazed doors in front of the bookshelves, a baize-lined sliding projection in the middle, and, in the lower section, four drawers on either side Price on request Private Sales | | | Made of five different luxury leathers in five colours, this rare Rainy Days Faubourg Sellier Birkin 20 handbag is a mini masterpiece. It is styled after the Hermès flagship boutique at 24 Rue du Faubourg Saint-Honoré in Paris, imagined on a showery day. Delightful details abound, from the orange shop awnings to the key-holder clochette, which is in the guise of an Hermès carrier bag Price on request Private Sales | | | | | Spotlight on | | | | Anytime, Anywhere DISCOVER PRIVATE SALES ON YOUR SCHEDULE | | ONLINE EDUCATION SIGN UP NOW, WHEREVER YOU ARE | | |
