Set of 10 espresso cups and saucers Chantal and Thierry Robert

Set of 10 espresso cups and saucers in enameled stoneware by chantal and thierry robert (atelier atch). Manufactured in the 70s and 80s. Each piece is unique. Gray-beige enamelling with a light frieze decoration on the cups. Cup diameter: 7cm. Diameter of the saucers: 12cm. In very good condition, note chips on the edge of a few cups but which do not call into question their use. Signed under the base of each cup. Two cups more than the set. The couple of ceramists worked from the beginning of the 70s until the end of the 90s in the department of maine-et-loire.
