This publication is an in-depth study on sign design. The fifty-plus projects were carefully chosen to feature diverse aspects of the discipline, leaving virtually no terrain uncharted in the field of wayfinding and signage. Interviews with the world's most prominent design firms and sign experts reveal candid comments on the inspiration behind their work, the surprising challenges they faced, and their reflections on their final products. Chapters are divided by sign locations, and each one features an insightful sidebar exploring a graphic element of sign design.
