Limoges Fragonard Porcelain 4 footed trinket box depicting a courting couple, age :1900-1940 in all my research it simply says "depicting a couple" so there's no info on who they were

Here's a similar product so you can make an estimate on how much its worth

Looking on the internet, this signed name led to a deluge of images, which are commonly called Fragonard Courting Couple or Fragonard Love Story, on plates, teacups, brooches, and vases. Apparently, these courting couples were inspired from the work of artist Jean Honore Fragonard (1732-1806). Fragonard was a French painter of the Rococo style who was popular in the latter half of the 18th Century, around the time of Marie Antoinette, Louis XV and Louis XVI. Rococo painters featured pastoral landscapes and incorporated in their paintings myths of love, cherubs, cupids, venus and mythical creatures. Portraiture was very popular among the Rococo painters and featured aristocratic courting couples on leisurely outings. Although the couples that I’ve found on china plates, teacups, and vases appear to be innocent courting lovers, some works of the Rococo painters’ depict some naughtiness in their pastoral scenes.

It seems that the French Revolution put an end to many of the careers of Rococo painters as their aristocratic patrons no longer could support them. This was not, however, the end of the Fragonard Courting Couple which has continued as a motif to this day. The first great revival of the couple was in the late Victorian times when they appeared on hand painted brooches and in miniature paintings. Later with the Victorian revival in the 1980s the couple returned once again on brooches, china, teacups and vases

Apparently the box was hand made and also hand painted
