If anything they're as good as, if not better than, the hosts of art cards in most premium and non premium sets these days.
I might double dip.
Are there any nice ones in English, just wondering?
Probably not. I think I saw a Labyrinth one a few years ago. Or was it Pans Labyrinth?
There were a few US digibooks, that had English text, usually they were excerpts from bigger art and making of books.
Mostly from Warner. Like Blade Runner, Falling Down, JFK, 300, Gettysburg, and Gods and Generals, Full Metal Jacket, Little Shop of Horrors, but also The Big Lebowski, E.T., Hansel and Gretel, and that New Line Masterworks Collection series, with Saving Private Ryan, Top Gun, Star Trek, Forrest Gump, The Godfather.
Spanish digibooks had mostly photos, or 100% photos.
French ones were nice, but text in their language.
