This lovely perfume bottle was made by Baccarat Glass in France at the turn of the century for The House of Guerlain for Guerlain L'Heure Bleue perfume. Each bottle was hand made with a matching stopper and the bottle and stopper are etched with the same number showing the stopper was made to fit just this bottle.
The bottle is in Excellent Condition, the label shows some ware and the stopper has flea bites around 1/3 of the edge. I have taken a 20x scan of the bottom so you can see the matched etched number and the flea bites.
Guerlain also had this same design of a bottle made for Mitsouko in the 1970's but it was not made by Baccarat.
