LONDON – The Winter Collection is a testament to the eye of one of the art world’s great connoisseurs. John Winter’s breadth of knowledge, from painting and drawing to sculpture, furniture and other decorative arts, and above all his beloved Florentine Doccia porcelain, was phenomenal. Highlights include two Florentine Baroque reliefs by Girolamo Ticciati, an assemblage of designs by the great 18th-century goldsmith Luigi Valadier and drawings by the likes of Jacob Jordaens. These are joined by 19th-century ceramics and terracotta and wax and pencil sketches by the leading lights of 19th-century sculpture.
