35mm color slide of two porcelain marks on the plate from the Catherine the Great Service in Slide 56. One mark (3 dots) is for Jean-Baptiste Tandart aîné (the elder; 1729–1816, active 1754–1800 or 1803), who was one of the “most skilled flower-painters” of his era (Eriksen and De Bellaigue 1987, 96). The gilder’s mark (cross-hatched lines at the bottom of the image) is for Michel-Barnabé Chauvaux aîné (the elder; also known as Chauveaux, active ca. 1753–88), a “gilder and painter of ornaments” (Tardy 1981, 533). The number 56 is handwritten on the slide.
