For the past fifteen years, I have traveled extensively to historic locations connected to the development, testing, and legacy of the nuclear age. The artifacts I’ve collected each carry a unique connection to pivotal moments in global history—moments that shaped scientific progress, geopolitical dynamics, and the modern world as we know it. These items are not only rare and difficult to acquire, but many come from sites that are now restricted, decommissioned, or altered over time. Together, they represent a tangible link to an era defined by innovation, tension, and profound change, offering collectors an opportunity to preserve and engage with history in a truly meaningful way.
