This beautiful vase is a lovely example of German mid century glass. It is not the most rare piece of glass design, but still very beautiful and attractive. Ingrid Glass, or in German Ingridglas, or Ingrid Glashütte, Ingridhütte was a glass manufacturer based in Germany. It was founded in 1960's and possibly went bankrupt in 1979. This is not the most famous piece from Ingridglas which is mostly known for a line of vases that resemble bark.
