Three paintings by Lucian Freud — each reflecting a key moment in his artistic evolution

This portrait of Isabella of Portugal is a copy of one made by Titian. The Venetian master, having been commissioned by Charles V, Holy Roman Emperor, to paint a likeness of his late wife, produced three works in response. One of these, completed in the 1540s, was the now lost original of this picture, depicting Isabella in a black gown with the imperial crown by her side

How to Paint, a 1975 work by Anselm Kiefer, subverts the notion that art is something that can, in any straightforward way, be taught. A winter landscape at sunset, with rose and gold mountains above a riverside village, is overwritten with a flurry of black arrows directed at various elements of the work, each of which, one imagines, would have a helpful note attached

Estimate: £80,000-120,000

Louise Bourgeois’s bronze Avenza Revisited, conceived in 1968-69 and cast in 2008, takes its title from a town near the Carrara marble quarry in Italy. Evoking a strange landscape where rock meets flesh, the work calls to mind the artist’s words: ‘Our own body could be considered, from a topographical point of view, a land with mounds and valleys and caves and holes’

With their scrolled armrests, barley-twist legs and acanthus-carved detailing, these two late Regency armchairs in Scottish oak make an imposing pair. But perhaps their most impressive feature is the wool and silk needlework upholstery in blue and red. The fabric dates from‌ around‌ 1720‌, a century earlier than the chairs, making it a remarkable survival of a prized Georgian craft
