This is Star Wars: Frames, published by Insight Editions:
The ultimate limited edition, Star Wars: Frames brings together master filmmaker George Lucas's personal shot-by-shot selections from all six legendary Star Wars films. Limited to 1,138 copies and showcased in a sumptuous deco-inspired wooden box, Star Wars: Frames contains six books, each corresponding to one of the movies in the Star Wars saga....all six books reside in the beautiful wood-inlaid box, which is adorned with two exclusive high-relief sculptures of Darth Vader and Yoda...
Holy cow. This thing's big: 25.75 inches long, 12.25 inches wide, 13.5 inches tall. Each book is 44 inches across when opened. The weight of the whole shebang? A whoppin' 210 pounds. It'd take a Jedi to levitate that thing!
Thanks to everyone who wrote in!
