Jasba Keramikfabriken (Ransbach-Baumbach, since 1926)
Jasba produced wonderful shapes, structures and colours. Iconic, for instance, is the Cortina series, launched in 1956 and produced throughout the sixties. Next to such modern shapes and glazes, the old style of the interbellum remained popular, as can be seen in the broad distribution of items in the radically un-modern 'Dekor Essen', which was launched in the early '50s.
