1572 Dessert Cup - Napoleon III - 1/2 blown and cut crystal

From the end of the 19th century, probably from a large crystal glassware, unstamped, this dessert cup in 1/2 crystal blown and cut in good condition. No cracks or bursts with just air bubbles trapped during blowing and tiny micro-scratches of normal use. Cut with 22 flat ribs, double-button leg and smooth round foot with the presence of a large trace of the polished blower cane. Very old dessert cup with its small flaws making all its charm and authenticity. All of the many photos complete this detailed description. Very careful shipping and followed in relay point when possible given the current health context complicating home deliveries.
