“The Postal Service has a long history of looking to the stars as inspiration for its stamps, and for celebrating the innovation, science and technology it takes to get us there, which is why the ‘Star Wars’ droids are a perfect fit for stamps,” said Isaac Cronkhite, USPS chief logistics and processing operations officer and executive vice president. “These new Forever stamps represent more than four decades of technical innovation in the service of brilliant storytelling.”
