In François de Jullienne (1722–1754) and Marie Élisabeth de Jullienne (1724–1795), we see a beautifully composed portrait featuring the two subjects. The colors are soft and warm, with delicate pastels dominating the palette. François is depicted in a dark coat, while Marie Élisabeth wears a light, flowing gown adorned with lace.

The background is subtly painted, allowing the figures to stand out prominently. The painting is executed in oil on canvas, a common medium for portraits during the Rococo period. Coypel's technique showcases his skill in rendering textures, particularly in the fabric of the clothing and the softness of the skin. The dimensions are approximately 100 x 130 cm, making it a sizable work that commands attention.

The careful attention to detail is evident in the expressions and postures of the figures. Charles-Antoine Coypel was a prominent French painter of the Rococo style, known for his portraits and historical scenes. This work, created in the 1750s, reflects the elegance and charm typical of the period. An interesting fact about this painting is that it captures not only the likenesses of François and Marie Élisabeth de Jullienne but also their status in society, as they were part of the artistic and intellectual elite of their time.
