David Clayton James Gassaway has created some of the most incredibly haunting Cthulhu Mythos images I've seen in a long time. These are showcased in his 2012 Cthulhu Mythos calendar, and you can see a few in the gallery here.
Gassaway, also known as Daupo, explains:
Each is an original sculpture in polymer clay, hand-tinted in ink, and separately lit and photographed. All your favourites are here: Cthulhu, of course, and Dagon, the Mi-Go, Yog-Sothoth, and Nyarlathotep, plus lesser evils, like the Innsmouth brood, and Richard Pickman's models.
This is a limited edition calendar, so if you want one, you'd better order it now.
