The first Star Wars movie was released on May 25, 1977. Last year (May 2007) marked its 30th anniversary, Lucas Online/Starwars partnered with the United States Postal Service (USPS) to come up with a new set of Star Wars commemorative stamp designs and even dressed up some of the standard blue Postal Service mail collection box to look like R2-D2 (nationwide). And with that, they released this R2-D2 mailbox papercraft along with other cool Star Wars merchandise. This paper model is currently available at the official Star Wars site under the crafts and projects section, check it out.
