Small fine studio vase - presumably by Kuch

A fine studio art pottery vase - presumably made by Wilhelm & Elly Kuch - around 1970. The vase does not have the usual marking which can normally be found on the unglazed stand ring (but I do have a Kuch-floor vase with the same glaze). Height 12 cm/ 4.7'. Very good undamaged condition. A fine piece of contemporary studio pottery.
