Some of ya'll might know the name "Kalex the Omen" from around the internet. Recently he put together an OSR publishing label called "Mischief, Inc." It seems they have focused on adventures as their first products, and what is cool is that the adventures are compatible with most, if not all, original editions and OSR game engines.
As an act of good faith they have put their first adventure out basically for free. "The Tomb of Rakoss the Undying" is available as a "pay-what-you-want" product on RPGNOW; check it out HERE.
I have only skimmed it so far but its clearly got a high production value, and everyone likes seeing quality free products. You can find out more about Mishief, Inc. at their website HERE.
