Orrefors Palmqvist Faceted Lead Crystal Vase with a Young Woman a Flower and 2 Birds

The extraordinary Swedish glass artist, Sven Palmqvist, designed this portrait of a lovely young women for Orrefors Glassworks. The crystal vase was handblown, planed to create the flat, smooth sides, and engraved using the traditional copper-wheel technique. The vase is 5.25" tall, and the opening at the rim is 3.75" by 2.25". It is well-marked, Orrefors P 3354 D4 BE, so that means it was designed by Sven Palmqvist, it was made in 1965, and the engraver was Börje Eriksson, whose tenure at Orrefors lasted from 1947 to 1996.
I can't find a flaw on it!

The Orrefors story began in 1726, when an ironworks and smith was built near “the beautiful river that flows into Lake Orranäs” in the Swedish countryside. It was given the name Orrefors, which means “the Orre waterfall.” ("Orre" is the Swedish name for the black grouse, which is the bird seen on their iconic labels.) The foundry was converted to a glassworks in 1898, as the demand for iron decreased. By the mid-1920s, Orrefors was celebrated for the quality and beauty of its glass.

Orrefors employed master artists and craftsmen, like Sven Palmqvist, many of whom worked their whole careers of 40, 50, or more years with the company. Sven Palmqvist (1906-1984) was born in the glass district of southern Sweden and started his career with Orrefors in 1928, where he remained until 1972. In those years, he designed hundreds of engraved glass motifs. According to his daughter, to whom I am connected through an online glass group, he had a particular fondness for portraying people and animals. Palmqvist is known not only for his graceful and functional designs, but he is also known for his innovative techniques in glass production.
