Those look very nice! I started reading A Song of Ice & Fire when a coworker gave me her book club edition of A Game of Thrones sometime in the 1990s. I have all the book club editions now, to the most current one.
However, I recently purchased the Folio Society edition of A Game of Thrones. Let me tell you, it is, without doubt, the highest quality hardcover edition of any book that I own.
I plan to purchase the entire series of Folio Society editions, cost be damned.
But yes, I don't think old GRRM will finish it before he dies. Which author do you think has the chops to finish the story, should his estate enlist one? I'm thinking Tad Williams, but my nephew says Stephen Erickson.
