My colleague Christos Tsirogiannis has identified two polaroid images in the Medici archive which appear to show an Etruscan terracotta antefix offered at Bonhams London as lot 14 in its forthcoming 30 November Antiquities sale. The provenance provided by Bonhams is ‘James Chesterman Collection (1926-2014), formed in the UK in the 1970s-2000. With À la Reine Margot, Paris, acquired in December 1986’.
One of the polaroid images is attached to a Hydra Gallery form, with the handwritten ‘v. Londr’ indicating the piece was intended for sale in London. Medici opened the Geneva-based Hydra Gallery in 1983, so presumably he sold the antefix sometime between 1983 and 1986.
Bonhams has withdrawn the piece from sale.
