One of the highlights at Lempertz in Cologne on November 15 is a set of nine late-18th century scagliola panels.
Of varying sizes – the largest measures 2ft 9in x 3ft 4in (86cm x 1.02m), the smallest (an obelisk) 2ft 10in x 5in (87 x 13cm) – they depict views of a harbour, various palaces and other architectural scenes and elements.
