Be careful. The way this thing is put together, the pages are bound in so close to the spine, you've got to twist and turn the book to read some pages. And forget about getting a full view of the artwork without cracking the spine.
It is a very firm spine. But I found that pushing it flat doesn't seem to damage it in any way.
As for the book itself? Looks to be something pretty special indeed! Saving it for the weekend though...
Anyone else have time to dive in yet? Interesting how OGNs don't seem to get reviewed much but glad I can go in with only my own perspective.
