The omnibus edition (Volume 1) of the first 35 comics in the DC Vertigo series
Lucifer. It has bonus content as well, including a foreword by Neil Gaiman (original
Sandman universe character creator) and an introduction by Mike Carey (the writer - I think it's a "writer" and not an "author" when it's comic books?). It's a beautiful book with vivid printing on good, glossy paper. It's a little impractical for reading due to the heft (comic book sized, about 2-1/2 inches wide); 35 issues takes up a lot of paper! But I can read it sitting at the table with no problem.
