Map Like the OSR Crowd

Dyson Logos is famous within the OSR RPG crowd for his blog and distinctive style of adventure maps.

Today I saw he has composed a three-part tutorial for how to copy his style.

Michael Wenman, an OSR mapper of whom I have not previously heard, decided to do the same thing.

Fun!

You can even currently download Swords and Wizardry Complete for free.

UPDATE: I found a (probably illegal) web-page copy of Matthew  J. Finch's free PDF  A Quick Primer for Old School Gaming, which provides a much better introduction to OSR RPGs than any Wikipedia article!  Now no account registration needed to read the essay.
