Before laptops and cloud storage, the heartbeat of business ran on typewriters, filing cabinets, and rotary phones — and advertisers made them shine. This collection spans more than a century of office innovation, from polished mahogany desks and mechanical calculators to sleek copiers and early computers. The ads reveal not just the tools of productivity, but also the image of professionalism each era sought to project. A fascinating resource for collectors, design enthusiasts, and anyone curious about how the workplace — and the way we sold it — has evolved.
