What can you do if you bought one of these prints? Follow this link to the Department of Justice where you can file a complaint. http://www.usdoj.gov/usao/iln The website also contains many more details about the case.
The Feds are seizing assets of the defendants that may total 4 million dollars and you might be able to get restitutions paid to you as a victim. But that being said realize this case is just starting and that could take years. You should file any complaints now; this will help you later on if you are a victim.
