Here's what replaced the 'generic' mural a couple of weeks later. Leno is up front and (almost) center.
Since this photo was taken, the small photo of Conan O'Brien has been replaced by Leno while the large Leno picture has been deleted entirely. There are quite a few out-of-date personalities on the mural. With changes in programming, it seems this kind of mural would need updating pretty often.
