Ever wonder what happens to the things that never make it to museum exhibits—the artifacts without labels, the treasures waiting in quiet corners of warehouses, or the boxes sealed with stories no one's told yet? The Hidden Treasures Department invites you into the sunny side of obscurity: the world's unclaimed wonders that quietly safeguard our collective memory. In this uplifting field guide, readers are taken on a positive, behind-the-scenes adventure through archives, evidence lockers, university basements, airport lost-and-found vaults, and forgotten museum storage rooms. But rather than dusty gloom, what you'll find here is vibrant human ingenuity—how caring people everywhere protect, organize, and rediscover what others have overlooked.
