"In 1949, five years after its disappearance from the Metropolitan Museum of Art, a small, fourteenth century wood panel of Saint Thomas attributed to the workshop of the Sienese painter Simone Martini was returned.  The thief either was unable to dispose of it, grew tired of it, or became remorseful.  He wrapped it in a few layers of tissue covered by brown paper and mailed it back, with the museum's address in block letters and a fictitious return address."
