René Lalique "Penthievre" vase made in 1928 in molded clear glass with sepia patina.
Engraved "R.Lalique France" signature on bottom.
Most of time, the rim of this model is reduced. Never buy this model if rim is less than 13 cm of diameter or negotiate the price because you'll have a vase with polished rim.
The model I'm offering to you has a 13.5 cm diameter rim.
