Orrefors Rectangular Crystal Vase

This lovely and unique Orrefors vase (#D3658-991) is from my mother's cut crystal collection. She was born in 1912 but I don't remember when she acquired this piece. It's made by Ingeorg Lundin (1921-1992) who worked at Orrefors from 1947-1971. Her identifier is "D". On the bottom, it's inscribed "Orrefers D 3658-911" The vase is rectangular in shape, 6" tall, 6" wide at the top, 5-3/4" wide at the slightly curved bottom and the opening is just over 2". The glass is 1/4" thick and very clear and shiny. The beautiful cut design on the front sparkles and shines from the front through the back. There are some very minor one flea bite and scratches on the bottom, otherwise, it's in perfect conditions
