The Crumpled City map needs no folding skills. Just stuff it into its handy sack while you explore the city.
Emanuele Pizzolorusso designed this amusing "Crumpled City" map, which might be an ideal gift for those among us possessing neither smart phones nor the patience to properly fold a traditional map. One merely crumples it into a ball and stuffs it into its sack.
Maps are available for London, Paris, New York, Rome, and Berlin. From the looks of them, they should withstand neglect under rental car seats and at the bottom of purses. Clever.
