Welcome, Simpson family, to the Pantheon: Reuters reports that the U.S. Postal Service plans to issue stamps featuring the Simpsons later this year. The 44-cent first-class mail stamps will feature the nuclear family—Homer, Marge, Bart, Lisa, and Maggie—and will be designed by the show’s creator and executive producer, Matt Groening. The Simpsons is currently primetime’s longest-running comedy and will celebrate its 20th anniversary this year. The stamps will be unveiled on April 9.
