I picked up the Teratic Tome on PDF a while back.
I liked it. So I decided to pick up the hardcover too.
It fits in nicely with all my other 1st edition-ish books.
The author, Rafael Chandler, did a really good job of capturing the look of the 1st ed books.
Maybe too good of job in fact. In any case it fits in nice with my books as a Monster Manual 4 or Fiend Folio 2 (if Monsters of Myth is MM 3).
What really swayed me on this is the fact I am running a 1e game with my kids and I could use a couple of these.
If you buy the PDF you get a coupon to get hardcover at $6.66 off. If you buy the hardcover at full price you get a free PDF.
Pretty nice really.
