Luke Skywalker, Yoda, Darth Vader and, of course, R2-D2 are among the unforgettable Star Wars characters debuting on 15 new 41-cent postage stamps unveiled today at Grauman's Chinese Theatre in Los Angeles, where the first Star Wars movie opened nearly 30 years ago.

The commemorative stamps feature images from all six movies in the Star Wars saga: Luke Skywalker; Han Solo and Chewbacca; Princess Leia Organa with R2-D2; C-3PO; Yoda; Queen Padme Amidala; Obi-Wan Kenobi as seen in Episodes IV through VI; Anakin Skywalker battling Obi-Wan Kenobi; Darth Vader; Emperor Palpatine; Darth Maul; Imperial Stormtroopers; Boba Fett; the Millennium Falcon; and an X-wing fighter.

The stamps will be released at a first-day-of-issue ceremony on Friday, May 25, at Star Wars Celebration IV, the biggest Star Wars event in the galaxy, at the Los Angeles Convention Center.

"Star Wars fans everywhere will delight in the issuance of these exciting new postage stamps," said David Failor, executive director of Stamp Services, U.S. Postal Service, who hosted the stamp preview.

"Because of the movies' popularity, we believe these stamps have the potential of reaching the blockbuster status of the Elvis stamp, a milestone only the Force could attempt to surpass. The Star Wars films have timeless qualities that cross generations, just like the United States Postal Service," said Failor, who made the announcement of the new Star Wars stamps along with R2-D2, Darth Vader and Howard Roffman, president of Lucas Licensing.
