Art Theft encompasses individual thefts of art work, state sanctioned art theft, and the smuggling of antiquities. Occasionally, thefts are "commissioned" by private collectors who desire a certain piece. After a commissioned theft, the art work vanishes and is usually never seen again. Stolen art, obviously, cannot be publicly displayed so the price thieves receive for it is much lower than market value. Some art is so valuable, however, even a discount of 95% to the fair market value can net a large profit for the thieves.
