Lunéville K & G Coffee Cups - Early 1900s

Set of 2 old Luneville coffee cups - vintage. Good condition. (they are not chipped, but over time they have become a little stained on the inside, one more than the other) They are made of earthenware and are stamped as follows: raguenau. k & g. lunéville. france. For your information, this Lunéville K & G stamp (Keller and Guerin) allows us to know that they date from the early 1900s.
