Use a map in your artwork. As a background for an art journal page or artist trading card, as an element in a collage. You could use it simply for color or texture. Or you could use it to tell a story... i.e. a map of a specific place, an imaginary map, a map describing a place or the setting for a dream.
Think of all sorts of maps. Subway maps, maps of botanical gardens, maps of dreamworlds, a map in the back of your favorite sci fi novel.
There's an index to all of the Daily Paper Prompts.
