At least in San Francisco, that is.
Yes, starting Saturday, November 17, you'll be able to buy Marie Antoinette's perfume in the US to coincide with a new Marie Antoinette exhibit at the Legion of Honor. The exhibit (the only one outside France) will run until February 18, 2008.
The Legion of Honor gift shop will be selling the juice (made in France, naturally, by Beaute Prestige International/Shiseido). The de Young Museum gift shop in SF will also carry the perfume. Again, the juice (which is a pure parfum), based on original formulas and reworked by Francis Kurkdjian, is a floral composed of 100% natural essences.
Pricing is unknown, along with details if they will ship, but you can always give the Fine Arts Museums of San Francisco gift shop a ring at (415) 750-3642.
