Wow this things package is light as hell. Its purty, and the bonus dbl-sided poster that GS threw in is nice, however.
From the looks of that unboxing video, the artbook is standard 4-5 issue graphic novel size (single TPB volume of Walking Dead or New Avengers, for example). Can't speak from experience just yet, since my copy is still wrapped in plastic for the time being. Going to stay that way until I can work out any possible buyers remorse.
Still....damn pretty to look at.
