Sorry to be so late to the party- your vase was made between 1948 and 1954, during the six years that Tirol Glas was made under this label. After bankruptcy and a major fire in 1939, the Loetz company operated as Kristallglasfabrik Spiegelau GmbH), directed by Karl Baumann. In February 1942, the company was bought at auction by Julius Altmann-Althausen, whose son Kurt married the eldest daughter of Friedrich Spaun, Maria Luisa. This company, Glasfabrik Klostermühle vorm." J. Lötz We., Inh. Julius Altmann-Althausen, was liquidated in 1947; however Julius Altmann-Althausen set up a new glass works in Kufstein in 1948 called Tiroler Glashütte Altmann Althausen, Johann Lötz Enkel KG. It was this company that was responsible for this vase, and the label attached. The company operated for only six years. In short, while it has the Loetz name on the label, and there is a corporate line of succession, the company and the glass it made had no real technical or artistic connection to the company formerly known as Loetz Witwe.
