Cards by Michael Johnson of FontStruct is a free novelty display font built around chunky, outlined letters set inside individual playing-card shapes. The squared forms have rounded corners and a clean, mechanical stroke. Each card tilts and overlaps the next.
Card-game graphics are the obvious fit, especially for tabletop packaging, children's activity sheets, and playful event posters. In publishing, the framed letters can turn a magazine heading or puzzle-book cover into part of the game imagery.
