Eaglemoss does not sell these in the United States, presumably due to licensing issues, but in several countries, it sells these DC Comics Graphic Novels and The Legend of Batman collections, similar to its Star Trek Graphic Novels collection.
Customers sign up for a subscription, and every two weeks receive a new volume in the mail. As can be seen in the images below, the books’ spines form themed artwork (the Alex Ross image looks amazing in this format…much better than almost anything DC Comics has ever done with the multiple volumes of its omnibus version of comics).
