Tebax2k posted something in resources which I have used before, the Valley of Kings project. I thought it would be a good idea to go ahead and post a map I based off of that sites images... I did it a while ago, and while there are a few things I might to differently today (like use crosshatching instead of the gaussian blurr effect) I still am quite satisfied with the result.
The font used for the chamber descriptors is Belwe, an OTF style font.
