Badonviller cups from the 70s

Set of 12 ceramic cups with a pretty beige glaze decorated with a brown floral decoration, as if imprints of dried flowers had been taken. It is a service from the badonviller factory, stamped under each cup, whose history dates back to 1900 with the construction of the factory and incredible social conditions for the time: profit sharing, retirement fund, mutual insurance with compensation in the event of illness. We can make out a handwritten mention, which blends into the decor, like a signature, perhaps the signature of the artist who created the decor, because this company often worked with recognized artists, but I was unable to find more information on this subject. The decor is reminiscent of a production from the 70s. They are in very good condition, no cracks or chips. Perhaps a few chips under the bases but it seems to me that these are more original irregularities. They measure 5.5 cm in diameter and 7 cm in height.
