As part of the hoopla surrounding the 30th anniversary of the first Star Wars movie, the US Postal Service is using stickers to transform some mailboxes into likenesses of the friendly, valient droid R2D2. The mailboxes will be used in approximately 200 cities. For more information on the campaign, check out the USPS Jedi Master site. At ePromos we need to figure out a way to combine our mailbox stress ball with our robot stress ball. We’re working on it.
