The Society owns a facsimile copy (3 volumes) of the Leonardo da Vinci drawings. The originals are in the Queen's Collection at Windsor Castle.
Prof. Susan Standring has written an interesting account of the volumes:
Currently the 3 Volumes are available for viewing in the Gordon Museum at King's College, London.
