Fairy Lamp - French Lithophane

I love lithophanes, especially when they are fairy lamps and are colored. Many lithophanes are German in origin but many other countries produced them as well. This example is French, it has three scenes, the original pottery base, and is stamped with the makers mark, a sickle with the initials "P.R.". I have researched the maker's mark but there seems to be some disagreement as to what the PR stands for so I won't report what I have found. If anyone has conclusive evidence what the PR stands for, I would like to see it.

I have included photos of the scenes when they are lit and one example of one scene with natural lighting. I have also included a 1888 Stembridge (British Importers) advertisement that refers to them as "Bijou Transparencies."

This may be the find of the year. :-)
