Fantagraphics have long been one of the best if not THE best publisher of English language comics. DC, Marvel? Not even close. Anyways in the last few years they have branched out into this sort of thing.

Other publishers probably do this but I haven't seen it but it very well bridges the gap between seeing a photo of the cover of a book to what handling the book will be like and call me a weirdo but the physical heft and weight of a well bound chunk of paper is something I love and hanker after.
