Porter flute from the beginning of the 20th century

Height 20.5 cm. The beer glass is mouth-blown with fine lines in the glass from the glassmaker's tool. It is faceted on the lower part of the cuppa, which rests on a ball above the short stem. We have not been able to find the glass in any Danish catalogue, but Aalborg Glasværk has produced similar glass. The glass is in perfect condition. Item number: 10972
