Modernist vase west germany by bay keramik

Here is a very rare modernist vase from the 60s manufactured by Bay Keramik in West Germany. Marked W.Germany 274/30. (274 for the model and 30 for the height according to the usual code). This model was made in limited series and is very rare: I have seen only one other for several years and not with this black and yellow / orange very design and graphic. No splinters or knocks or cracks on this beautiful vase.
