Mutuel is recorded at Vincennes and Sevres as a painter of birds, landscapes and edgings 1754-1759, 1765-1767 and 1771-1774. His mark changed in style over a period of time, from that of a very specific compass to a more stylized inverted V, this last found on pieces of 1771-1774 for which he was responsible for the edgings. Given that the present coolers each also bear the mark of a flower painter and a gilder, they serve as documentary evidence for the development of Mutuel's mark.
