The Royal Mail is so much cooler than the US Postal Service. Not only has it released several series of stamps celebrating some of England's Rock legends, it has gone above and beyond in promoting them ,literally in the case of the recently released (story) David Bowie stamps. 52 sets of the stamps (the number chosen because it represents the years of Bowie's career) were attached to helium balloons and released into the atmosphere. All are marked with a special lightning bolt edition of the Aladdin Sane stamp. The location and direction of each balloon will be updated in hints posted to RoyalMail.com every two days so fans can enter guesses as to where they will land. You can also watch the stream of that balloon's flight on the site. Those who guess the most accurately about the landing points will be rewarded with First Edition stamp sets.
