I was looking at the 2011 Ennie Awards for Cartography, and the silver award winner was 'Bookhounds of London' - a Cthulhu adventure / sourcebook set in London in the 1930s. I really wanted to see the cartography, but couldn't find any screenies of it until

This is for the collector's edition, but the reviewer flips through the book at about 2:45 in the video. The cartography looks absolutely stunning and the production values look like they are second to none.

I'm off to order my copy now!
