tall spatter vase

I assume this is Czechoslovakian but that is about the extent of my ability. I have attempted to match it up with a few reference sites but have had no luck - guidance will be appreciated.

Vase stands 10" (25 cm) tall. The diameter at the top is 3 3/4" (9.5 cm). The exterior is not cased, giving the piece a tactile texture. To me, it looks like slices of orange-cased-in-yellow canes were applied to a clear ground that was blown into a mold, pulled, cut from the top, then cobalt blue handles were added to make the colors pop. The foot is slightly concave and has a diameter of 3 1/4" (8 cm).
