G.E.H.A is celebrating 250 years of postal service by partnering with the Smithsonian Postal Museum to recognize great moments in postal history. John T. Jackson, a postmaster in Virginia, served his community for more than 48 years. His movable post office unit, with its 30 mail-sorting shelves, stands as a testament to the adaptability and dedication of postal employees. At G.E.H.A, we're inspired by such stories of service. #250years #postal #history
