Cardboard and paper are more than just the medium for the My Cardboard Life. The webcomic imagines that its characters are actually beings of cardboard and paper – with all the powers, limitations, and silly jokes that go with it.
Along with Marlowe the Monster (previously), Philippa Rice's My Cardboard Life is one of the craftier comics online. But where Marlowe was about creating dramatic scenes with cardboard and clay, Rice uses My Cardboard Life to explore the metaphysical possibilities of her medium. Her comic operates under the conceit that her characters – and everything around them – are actually made of paper, cardboard, marker, and pen, and explores what life in that universe might be like.
