Monster Zero x SciFi Japan - Archive Only

Was wondering how rare these are nowadays. ...I've heard the fetch a mint now, if they even surface. Weird now Godzilla books tend to get so expensive.

I remember when I first received this back in the day (I believe I was in my final year of HS). I ordered it through G-Fan and it was delivered in the mail, and the local douchebag post officer jammed it carelessly into our mailbox, and as a result the side binding got ripped up a bit Otherwise, it's still one of my favorite books that only Ryfle's Japan's Favorite Mon-star can compare with....but again, it's long overdue for an *updated* English book covering the series beyond GvsDestroyer..
.
As as what it goes for today....no idea, but I would say be prepared to spend minimum $100 as a starting point.
