http://ohdannyboy.blogspot.com.au/2012/05/joe-simon-fbi-and-strange-case-of.htmlVery interesting article about original art shenanigans back in the 70s. A bunch of art went missing when DC moved offices & then showed up for sale from local art dealers who had very sketchy stories to tell about how they got their hands on it when Joe Simon went after them to get his work back.
Particularly fascinating are the FBI documents printed along with the article (key names have been redacted, looks like they were acquired via the Freedom of Information Act).
