The US Postal Service has released its schedule for stamps for 2011.

Our favorite is the Pixar collection – featuring Buzz Lightyear as well as images from Ratatouille, WALL*E and Up.

Other highlights for 2011 include stamps honoring the Merchant Marine, Mark Twain, actors Gregory Peck and Helen Hayes, American Scientists, Latin Music Legends, civil rights activist and politician Barbara Jordan, and President Ronald Reagan. A souvenir sheet commemorating the 150th anniversary of the Civil War should thrill history buffs.
