It could be worth it just for the Alan Lee art. There are 11 (including the cover) "fresh" Alan Lee sketches. Entertainment Weekly put out 3 of them, but I'm never disappointed by Alan Lee's art, and prefer him to John Howe. I don't mean that as a slight against Howe's Tolkien art either, it's just over saturated in my opinion. It's everywhere since PJ's films.
But the Alan Lee art is I believe the only thing you could call "fresh" about it, aside from Brian Sibley's commentary.
