Over the past five years, designer Jug Cerović has produced 40 metro maps using a common, standardized design language. Now he’s launching a Kickstarter campaign to gather them all in a single collection, called One Metro World, in both book and mobile app form. The book in particular sounds lovely: hardbound, printed on quality paper, and with stories about each map—plus 15 of the maps get additional schematics “highlighting network peculiarities as well as map design choices.” [Mark Ovenden]
