Tea set in hand-painted Limoges porcelain

Hand-painted limoges porcelain tea set. Floral motifs on a raspberry-colored background. Each cup has a different floral pattern and each piece is signed by the artist. This service belonged to my grandmother so it is probably from the early twentieth century. It consists of 12 cups and 11 saucers (maybe a 12th that I would not have seen in all wrapping papers?), a teapot (about 17cmx13cm), a sugar bowl and a milk jug. Everything is in impeccable condition without chipping.
