Spread some holiday cheer! Or fear! (Or at least a little concern.) Black Mass Appeal’s own Tabitha Slander has created three winter holiday themed carts that appeal to the more diabolical side of the season. This is a set of three cards, one of each design: Cthulhu’s dreams, Krampus’s greeting, and Baphy in the manger. (Individual cards available here.) Cards are postcards, 4 inches by 6 inches. Cards will ship last week of November.
