I'm going to revive my Vintage Vault series on beautiful perfume rarities.  that I hosted on my old blog site.  Here's two beauties and what I wrote about them previously: These Fritzsche bottles are very rare.  One perfumer told me the musk  one is museum quality due to its rarity and design.  I've also a suspicion that the Sweet Birch one contains the pre-IFRA really great salicylic-rich sweet birch that is the type that was used in leather fragrances such as Cuir de Russie.
