Your cup was made by Lewis Straus& Sons factories !! The above will give you the history !! Didn`t read it all but looks very interesting !!

France is the word printed below and outside the blue circle, inside the circle at the top is has the letters “L S & S”.

I can barely read the Limoges France on the blue mark,, can you tell what it says at the top of the mark !! There were so many mfrs that without knowing what that is,, can not find the maker !! Generally cups like these run in the $20. to $25. range and that is the high side !!

I have attached a picture of the bottom of the cup.

I have been off for a while but will try to help !! Mustache cups do not normally have a pattern name unless they are part of a set !! What mark is on the bottom of your cup ?? Can you take a pic of it please ??
