The U.S. Postal Service and Twentieth Century Fox Licensing and Merchandising announced The Simpsons will be commemorated on 44-cent First-Class Mail stamps in 2009. Featuring Homer, Marge, Bart, Lisa and Maggie Simpson the stamps have been personally designed by Simpsons creator and executive producer, Matt Groening. The show is currently the longest-running primetime comedy in television history and is celebrating its 20th anniversary throughout 2009, which will culminate on January 14, 2010. A sneak peek of the stamps will be made available on 4/9 on www.usps.com. At that time, the Postal Service will announce the date the stamps go on sale and how to pre-order stamps.
