Leading the Annette McGuire Cravens collection sale was this marble Cycladic head, left, from the 3rd millennium BC. The head, from a figurine, is a typical example of this much-admired ancient sculpture from the Aegean area of the Mediterranean.
It stands 5½in (13cm) high and is of so-called late Spedos variety. It has a provenance back to the late 1960s/early 70s when it was acquired by Dr Charles Alexander Best of Toronto, a member of the Canadian parliament and son of Dr Charles Herbert Best, one of the co-discoverers of insulin.
