Six vintage blue and turquoise ceramic espresso cups and saucers

Period: ca. 1960s-70s there are six cups and saucers. They are made of ceramic that has been given a dark blue to black glaze into which accents of turquoise have been artistically added. No two cups or saucers are identical and all have their own unique designs. These are typical of the mid-century vallauris style, but they are unmarked. Condition: very good. No damage. Looks barely used. Dimensions: saucer 12 cm in diameter, cup 6.5 cm in diameter, 5.5 cm high together.
