We don't get this type of crime often.This smells highly of an inside job. It is highly unlikely your average or even above average street thief would grab these as they are all abstract, or nearly so, works. They would have no idea of how to fence such works anyway.

It baffles me that anyone with this value of a collection would not have it insured. If one can't afford to insure it wouldn't one sell it rather than run this risk?

The 19 works of art were stolen sometime between April 27 and 29 and may have been taken by international art thieves, according to the FBI.

The FBI did not say where the artwork was stored or identify the owner, but said the artwork was not on display. The art was not insured.

The stolen art has been entered into a national database of stolen artwork. A $5,000 reward is being offered for the return of the art, which includes a "Flowers" silkscreen by Warhol. The other stolen art includes works by Larry Rivers, Francesco Clemente, Philip Taaffe, Joseph Beuys and Peter Schuyff.
