The main set of 10 stamps features characters from the show in two worlds: the “Rightside Up” real world in red, and the “Upside Down” alternate dimension in blue.
Each pair of stamps, designed vertically, represents a different season of the sci-fi drama, starting with season one on the left.
David Gold, director of external affairs and policy, Royal Mail, said: “We’re thrilled to celebrate Stranger Things with this striking stamp collection.
“Each design captures the essence of the series – from its unforgettable characters to the eerie imagery that has gripped audiences worldwide – making this a true tribute to one of modern television’s most popular shows.”
The stamps also include a special UV feature: when illuminated with a UV light, iconic logos from the series become visible.
The ‘1ST’ denomination is styled in the show’s distinctive typeface.
A miniature sheet of four stamps shows the four friends riding their iconic 80s bikes.
Royal Mail collaborated with British illustrator Kyle Lambert, who creates posters for each season of the show.
Mr Lambert’s artwork has appeared on billboards, merchandise, and advertising campaigns around the world.
Set in the 1980s, Stranger Things follows the residents of Hawkins, Indiana, as they confront supernatural threats from the ‘Upside Down.’
The stamps and related collectibles are available to pre-order now at www.royalmail.com/strangerthings and by phone on 03457 641 641.
