Dewar whiskey glass, small size

Height 13 cm. Dewar is made at Holmegaard and Kastrup Glassworks in the period 1900 to 1940. It is described as a "whiskey glass with measuring cup". In addition to this un decorated version, it is also sold as a "private label", meaning that inns, taverns and spirits manufactures could order this glass with their own name, logo or slogan on it. This glass is a unsual little model, we have never seen before. Item number: 11823
