Couple issues with this episode. The whole nazis stole the painting and it has issues.... Nazis stole a lot of paintings..... That typically isn't the only thing associated with painting they stole... The other issue is telling a forgery from a pic...obviously it's a great forgery, but shoot, type up a little math equation, all info based on a PICTURE of the painting, and voila! All those decades of training and experience art experts receive can be thrown out the window. If this was even remotely possible, it would revolutionize the art world. I do suspend my disbelief a lot for this show, but this math fix was a bit too far fetched.....
