I have a painting from my grandma. It has Louis Rauret on the bottom and Le Refuge. On the top it says Paris Etching Society NY-USA. What can you tell me about this. When did he live, where is this picture painted of, when did he paint this painting?

I believe you mean RAMET instead of Rauret.
Le Refuge

During the 30's and 40's the Gallery was also a publishing house specializing in French etchings under the label "Paris Etching Society". The coloring of these etchings are quite exquisite. They often appear to be watercolor when they are in fact aquatint. Sydney Lucas contracted with French artists to publish editions of their work. After Sydney died in the mid 60's, his wife, Phyllis carried on the business, building on the Gallery's collaboration with Salvador Dali. The Gallery was the first North American publisher of his lithographs and published 26 editions of his images. Dali was a frequent visitor to the Gallery, and a friend of Phyllis Lucas, who died in 1995.

During his career, Sydney published thousands of images. Through the Paris Etching Society and his own prints, he brought art into the homes of people at all levels of income through his etchings, serigraphs, woodblock prints, restrikes and reproductions. The various subjects included Redouté and Prevost Flowers, Barraband and Gould Birds, Piranesi, French Landscapes, Urban Scenes, Women, Children, Animals, Hunting and much more.

These etchings can be found in many places and the value of them depends upon the importance of the particular artist who created the piece. These etchings are usually marked by one or more of the following, S Z L (within a triangle) for Sydney Zoltan Lucas, P E S or Paris Etching Society, or Camilla Lucas.
