Jean-Baptiste I Tilliard, maître in 1717.
The heart-shaped cartouche is a hallmark of the Tilliard workshop and was used by both Tilliard father and son. It has been suggested that there was a tendency at the Tilliard atelier during the period 1743 to 1766 to emphasize the corners of the back as is the case in the present lot, see P. Verlet, Les Meubles Français du XVIIIe Siècle, vol. I, Paris, 1956, p. 49. This strengthens the likelihood that these chairs were made by Jean-Baptiste I Tilliard.
