reference material

By snibe_8, in Arkham Horror Second Edition

So I'm looking to build a good game table with interchangable playing surfaces depending on the game I'm playing. I have a lot of time on my hands. I would love to create 3 dimensional buildings for the Arkham surface. Other than the Cthulu Mythos art book that FFG sells, does anyone know of any other good reference material for how this world looks?

The supplement from Chaosium for CoCrpg called "Arkham Unveiled" has a 3d map of Arkham (pull out and unfold) which I suspect this game board is based from, but it shows a lot more detail.

Thanks for the info, that's awesome. I'll check these out
