It may be possible even probable that the CIA did this but so what ?
As it turns out they did not have to do it much.
I was recently reading a book about money laundering and the chapter on art was one of the surprising parts. Many experts in money laundering have used art galleries and investments to move ill gotten money into legitimate accounts. If you have illegally acquired money such as from drug sales, one way to move it is to paint some crappy art and put it on display in a low end unpopular art gallery. Then pay some whiny art students at the local college to go buy it for ridiculous prices.
Apparently this sort of thing is done far more often than most realize and is a tough one for the police to track. It also explains why there is so much crappy art in the world.
Seems like the CIA may have wasted it's time.
