The United States Postal Service will be selling a line of stamps depicting characters from Disney-Pixar movies, beginning August 19th. The characters were chosen for their friendships and family ties. The new stamps are intended to encourage people to connect with loved ones through the mail. “The Send a Hello Forever stamps are a natural outgrowth of the Art of Disney stamp series issued between 2004 and 2008. Originally intended as a series of three annual issuances depicting friendship, celebration and romance, the Art of Disney stamps proved so popular that the Postal Service expanded the series to include the issuances in 2007 and 2008 to celebrate imagination and magic,” according to a Disney Consumer Products spokesman. The group of 20 stamps will include five different designs including Lightning McQueen and Mater from “Cars”; Remy and Linguini from “Ratatouille”; Buzz Lightyear and two of the green, three-eyed aliens from “Toy Story”; Carl Fredricksen and Dug from “Up”; and WALL-E from “WALL-E.” A first-day-of-issue ceremony will be held at the D23 Expo in Anaheim, Calif., with John Lasseter, the studio’s chief creative officer, and Ronald A. Stroman, deputy postmaster general. Forever stamps can be used anytime, even after the postal service raises rates. They are valid for the current first-class rate.
