Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things. Exits are all around us. They are the difference between travelling and arriving, being on the inside or outside. Whether signposted or subversive, personal or political, choices or holes we've fallen through, exits determine how we move around our lives, cities, and the world. What does it really mean to 'exit'? In these meditations on exits in architecture, transport, ancestry, language, garbage, death, Sesame Street and Brexit, Laura Waddell follows the neon and the pictograms of exit signs to see what's on the other side. Object Lessons is published in partnership with an essay series in The Atlantic.
