Modernist two-tone Czech enamel Glass Vase

A wonderful and very useful design. Modernist point of view with triangles and 1/4 circles in two color enamel glass. Yellow and black, quite rare really. I do not see these very often, and this one has quite a nice diamond shape.. It works perfect for a any floral setting. Most likely designed by Karl Palda. Very high quality enamel paint, not hand painted after.
