Inspired by the artwork of trading card games, and collecting.
Cardt is an ongoing project of hand drawn unique collectible cards. The name was created by overlapping the words card and cartoon. The two concepts have a shared history.
Cartoon (n.) 1670s, "a drawing on strong paper" (used as a model for another work), from French carton or directly from Italian cartone "strong, heavy paper, pasteboard," thus "preliminary sketches made by artists on such paper"
