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. Choose from Cthulhu’s sweet dreams, Krampus’s greeting, and Baphy in the manger. (Set of three available here.) Cards are postcards, 4 inches by 6 inches. Cards will ship last week of November.
