When you're so rich you don't notice your Picasso is missing

Billionaire socialite Wilma “Billie” Tisch is suing a Florida gallery owner for trying to sell a US$1 million Picasso that was stolen from her Manhattan home — sometime after December 2009, according to court papers.

Tisch, 88, only recently discovered the 1928 portrait of the famed painter’s mistress, Marie-Therese Walter, was missing.
