“Property of a Lady” is the name of the Fabergé egg in Octopussy (1983). It is also the third short story by Ian Fleming incorporated into the collection of short stories Octopussy and The Living Daylights. Moreover, it was also the working title for a rumored 1991 James Bond film starring Timothy Dalton, that eventually stalled indefinitely. Brosnan of course took over as 007 after that.
The Wikipedia page for the eggs is a great one to get lost in. 🙂
