Ray Hahn is a retired educator, but he has never stopped teaching. His decades of researching, writing and editing a newsletter for the South Jersey Postcard Club has been a world-class education in trivia. In addition to postcard collecting, Ray’s other interests include history, genealogy, and touring the world with his wife Marie. Ray often advises his readers to “Join me as we explore the world one postcard at a time.” Ray and Marie live in New Jersey.
