The beginning was humble, to say the least: The people at Flash Reproductions told the people at Up Inc about a cool new bookbinding technique. Intrigued by the possibilities, we brainstormed some ideas about how best to try it out. From there, we enlisted photographer Sandy Nicholson, and a critical mass of other partners, for a unique collaboration. The result? Together, we’ve created 0 to 100, a poignant glimpse of the true face of the human lifespan: 101 portraits of folks at every age, from mere weeks to a full century old.
