A map of Arkham

I'm up to date with my Inktober in Instagram, but I haven't scanned a single piece yet, so, as usual, I'll just post them in blocks afterwards. In the meantime, I'm uploading here a map I made of Arkham, according to every bit of information I could find online, from books, comics and games. I posted it in Twitter some weeks ago, but I like to keep it here because blogs allow indexing :)
