The Royal Mail issues a wide variety of special stamps commemorating popular culture, such as the X-Men, Terry Pratchett’s Discworld series, Harry Potter, Peppa Pig, and the heavy metal band Iron Maiden. Most recently, the government agency issued a series of eight stamps with some of the most famous and dangerous monster from the world of Dungeons & Dragons.
They’re available in enlarged versions suitable for framing and display in tasteful homes, as well as actual stamps that you can use to contact old-school off-grid players. My favorite is the mimic, which has become so common in popular culture that it was central to the anime and manga franchise Frieren: Beyond Journey’s End.
