I swear man, nothing gets past the OSR blogosphere. They were first to notice Gygax magazine, first to point out online retailers were getting ready to sell old D&D edition reprints (way before WOTC announced it), and now People Them With Monsters may have stumbled on the motherlode: www.dndclassics.com.
