Souvenir sheet as a companion to the Views of Our Planets stamp pane. Pluto is now officially designated as a dwarf planet. “At the time, Pluto was still considered a planet, and it was the only one in our solar system that hadn’t been visited by a spacecraft.” Postal Service Chief Operating Officer and Executive Vice President David Williams in dedicating the stamps. “In 1991, the Postal Service issued a Pluto: Not Yet Explored stamp that served as a rallying cry for those who very much wanted to explore it,” said U.S. Visit Our Planets Forever Stamps to view images of the stamps and background on the planets. The public is asked to share the news on social media using the hashtags #PlutoExplored and #PlanetStamps.
