There is a Cthulhu Mythos Sale over on DTRPG. This post is to highlight some of the OSR selections in the sale. I'll add another post over the weekend highlighting some Call of Cthulhu selections.
Astonishing Swordsmen & Sorcerers of Hyperborea (Compleat Second Edition) - what if AD&D were primarily inspired by Conan and not Middle Earth? Wonder no longer. "ASTONISHING SWORDSMEN & SORCERERS of HYPERBOREA™ is sword-and-sorcery role-playing at its pinnacle. Play an Amazon fighter, Atlantean magician, Esquimaux shaman, Hyperborean warlock, Ixian necromancer, Keltic barbarian, Kimmerian cataphract, Pictish thief, Viking berserker, or one of many other possibilities."
Silent Legions - anything from Kevin Crawford simply rocks :) Silent Legions is a game of modern-day Lovecraftian horror, one carefully designed to support sandbox adventures by hard-bitten investigators and fearless hunters of the dark. Its clean, lightweight old-school rules are compatible with the free Stars Without Number sci-fi game and give both GM and players a steady framework for plumbing the unspeakable secrets of the eldritch night. Now, after a successful Kickstarter with more than 1,100 backers, a Kickstarter completed a month early, this tome of dark secrets can be yours. Silent Legions isn't just about traditional Yog-Sothothery. Silent Legions is a creation kit, a toolbox in the Sine Nomine style for creating your own Mythos, with all-new deities, alien entities, foul magics, accursed artifacts, unaussprechlichen kulten, and diabolical dream-worlds to bedevil your players. These tools are system-neutral, so even fans of other Lovecraftian gaming systems can scoop them up to add a splash of fresh horror to their more familiar tentacular abominations. Not only that, but Silent Legions is built to help the GM create investigative adventures with minimal strain. Within these pages, you'll find a modular set of templates and adventure guides that help you snap together an evening's intrepid investigation and fit it neatly into your campaign setting. Like the Mythos creation tools, these guides are system-neutral and can be exported for any occasion when you need something wicked to this way come.

Sign me up! - "Eldritch Tales: Lovecraftian White Box Role-Playing in an OSR rule set with its roots in the Original version of the world's favorite RPG, but instead of exploring musty dungeons, characters in Eldritch Tales investigate Mythos horrors in the 1920s!

The Cthulhu Alphabet - Simply an excellent read -"The Cthulhu Alphabet is a collection of random tables to inspire your role-playing game, structured around an abecedarian theme. If you are a player navigating an uncaring universe, a haunted setting, or a horror-filled dungeon, you will find new ideas for your character and adventures.
