Britain's Royal Mail just announced that it's recognizing Game of Thrones with a 15-stamp collection celebrating the significant British contribution to HBO's hit series.

Ten stamps feature characters from houses Stark, Targaryen, Lannister and Tyrell. And five more stamps on a Stamp Sheet feature characters such as The Night King and White Walkers, plus the coveted Iron Throne itself.

The stamps are available for pre-order now, and in post offices across Britain beginning January 23.  Like the show, they're going to be popular. Some gifts and collectibles are limited to a run of 1,500, so if you're a serious fan, you may want to consider pre-ordering before disappointment crushes your heart like the ice of a Westerosi winter.
