Bosses at Britain's Royal Mail service announced plans for the 10-stamp set in January (17), making the late rocker the first musician to be recognised with his own postage series.

This week (begs13Mar17), officials attached 52 sets of the stamps, representing Bowie's 52-year recording career, to special helium balloons and released them into the sky.

They then encouraged fans to keep an eye out for the special edition "stamps that fell to earth", which all feature a red thunderbolt handstamp, similar to that from the cover of Bowie's 1973 record Aladdin Sane, for the chance to win limited edition versions of the postage, reports The Guardian.

The stamps have also gone on general sale, with the set including cover artwork from albums like Let's Dance, Heroes, and Hunky Dory.

Bowie died from cancer in January, 2016, aged 69.
