I could only help with Shalimar Extrait (from the 1960s??) in the black-white zig zag box in pristine quality. It was sealed and stored in a cool place. It has all the animalics in the base that made it so special.
I'm thinking of going to the Osmotheque myself next July. Does anyone know how it works with the donation of a vintage perfume, which is the access to the special fragrant treats?
