Do you guys recall if Wyrmworks was selling compiled sets of their maps as comb-bound books? I picked up a set recently including Dwarfen Crag, Capella's Asylum, and Gaming Maps, and Bricks and Bones II.
Curiously, the comb-bound book has cardboard bound into its pages too, but in the middle of each product rather than in the back between products. My assumption is that it's a home-bound "product"
