The original set I think was a numbered limited run, but they've released it a few times after. Each run seems to be somewhat limited or perhaps made to order. There are slight differences like the bookmark ribbon color, or cover color being lighter or darker browns, but otherwise are the same.

Its pretty nice, especially for me since I never had them all at the time I bought it.
The Book is rather large though, obviously.
