The Bohemian one with similar style decoration might be the vase that is on the cover of the book "Bohemian Glass Tradition and Present" by Antonin Langhamer. That particular vase has also black painted decoration in pointy patterns. It was a 1924 vase from the Bohemian glassworks at Klastersky Mlyn (that would probably have been Loetz Witwe?)
