Rhine wine glass in red lined crystal roemer nachtmann 21 cm

This sublime white wine glass - roemer is made of red crystal. This blown crystal model comes from the german nachtmann crystal factory. This wine glass with a cut leg and flared drink is perfectly transparent, it is a model of high quality. In crystal lined with a red parison, the drinker is cut with vertical and horizontal lines. Signed, this glass is in good condition; it measures 21 cm in height X 9.5 cm in diameter. I report small liquid stains.
