The Maison Lebrun works along with many private collectors, galleries, decorators, French and international museums, relying on the richness of its collection and its expertise in choosing the frame for their artworks. Orders of the most prestigious names next to anonymous clients are kept in the registers with the greatest confidentiality. 

 

The great names of art are part of the history of the Maison Lebrun, such as John Singer Sargent who chose himself in July 1917 the frame for the portrait of John D. Rockfeller that he had just finished painting. In the early 20th century.

 

The famous art dealer Joseph Duveen had many quality frames produced by Lebrun's workshops, for the impressionist paintings he displayed to his American collectors.

 

Jules Strauss, famous collector in the early 20th century, as a great donor of antique frames to the collections of the Louvre, chose from Lebrun the Tabernacle frame for The Virgin of the Rocks by Leonardo da Vinci.

​

From the beginning, Lebrun regularly collaborated with museums : the Louvre, the Musée d'Orsay,  great provincial museums such as the Fine Arts Museum in Lyon, Dijon or Angers. The National Gallery and the Wallace Collection in London, the National Gallery in Washington DC, the Metropolitan Museum in New York, the Sterling & Francine Clark Art Institute, the Liechtenstein Museum in Vienna, and most recently the Louvre Abu Dhabi.
