Reproduction of an album sheet at Wilton House on which many different drawings had been pasted in two columns. The sheet is believed to have contained drawings attributed to Franceso Melzi recording designs by Leonardo da Vinci. The sheet appears to have been dismembered: the top left drawing, consisting of heads of a woman and a man, was sold at Sotheby's in 1917 and later at Christie's, London, 5 July 2011, lot 4. According to the Christie's catalogue, the drawings by Leonardo da Vinci from which these Wilton heads were copied were formerly at Chatsworth, and the head of the woman is still there (2011; inv. 824D)
