The US Postal Service unveiled the upcoming Star Wars stamps yesterday; there will be a set of fifteen Star Wars stamps on a poster-like sheet released in May. Also, stamp fans can vote on their favorite stamp at that site. The winning stamp will them be reissued later in the year as "a single stamp."

I haven't been able to find any credit for the stamp art -- I suspect it's Drew Struzan, from his long association with Star Wars and because it looks like his style, but that's only a guess. Hey, Lucasfilm and USPS! Please credit the people who do the work!
