Story highlights Painting stolen from New Jersey home in 1976

Purchased for $50, painting could now be worth $1 million

The FBI returned the painting -- known variously as "Taking a Break," "Boy Asleep with Hoe" or simply "Lazybones" -- to the six children of Robert and Therese Grant, from whose house it was stolen in 1976.
