Felix Salmon on the Eggleston lawsuit: "At first glance this looks like what it is: one of the silliest lawsuits the art world has seen in a very long time. In order to win, Sobel will need to demonstrate two things, neither of which is true. Firstly, he’ll have to show that the value of his vintage Eggleston prints has been diminished as a result of Eggleston making a new series of much larger digital prints. And secondly, he’ll have to show that Eggleston had no right to make the new prints."
