4 vintage fat lava ceramic cups

The four coffee cups are in perfect condition, no accidents, no cracks or splinters. They are marked, on the reverse of the saucer, in hollow under enamel. They are thin, beautifully crafted, with textured foam enamel gray matt blue, blue looking darker in the photos than in reality. Saucers measure 13.5 cm in diameter. The cups 8 cm in diameter at the neck, and 4.5 cm at the heel, by 6 cm high. Very nice household ceramics. High quality French work from the 50s.
