That massive tome is the best 150 bucks I ever spent. And the best book regarding Star Wars, period. Plus, it's pre-SE, so there's no digital crap in it.
It's even got a number of photos from cut scenes as well as some of the oddball spin-offs like the Ewok movies and the Holiday Special. It's just downright fantastic. With that and Behind The Magic, you own most of the Star Wars universe.
Sadly, pretty much anything put out in recent years will be tainted by CGI additions.
