I decided to purchase this product and am pleased to announce that they have inserted the blank pages that Jeff mentioned. Unfortunately, I could only give 4/5 stars because the scan didn't line up the maps quite right, maybe about 1/8 or 1/16 of an inch off. Just enough to make you cringe a little bit. However, it doesn't prevent them from being usable. Especially since I print the maps out and cut/paste them together on parchment paper when I DM. (There is a tiny watermark with my name and order # on the bottom left. Very unobtrusive.)

I'm very happy with the product overall.
