To the casual observer, the term "money laundering" typically brings to mind a certain kind of criminal—maybe Pablo Escobar—who traffics in drugs and then "invests" the cash proceeds in a legitimate business—say, a laundromat—in order to "clean" his drug profits so they can't easily be traced.  This stereotypical kind of money laundering has been criminalized in the United States since the 1930s. But today money laundering takes many forms and can be found in unexpected places, including the fine arts and antiquities markets.
