Superb 1930's Czech/Bohemian multicoloured art deco style glass vase

  

Superb 1930's Czech/Bohemian multicoloured art deco style glass vase. This design was for a long time attributed to Kralik, but research by others has recently revealed that it was apparently made by the Ernst Steinwald glassworks, up until 1938 when production was moved to the Franz Tomschick glassworks.
