From Bulbapedia, the community-driven Pokémon encyclopedia.
A poster is a type of item used to decorate bedrooms in the Generation II games and Secret Bases in the Generation III games that take place in Hoenn.
In the second generation of games, there are four kinds of posters:
At the start of the game, the room is furnished with a Town Map. Found in many other locations as well, looking at this will let players view the region they are in.
However, by using Mystery Gift, players may receive one of the other three posters: a Clefairy Poster, a Jigglypuff Poster, or a Pikachu Poster, each of which has an image of the appropriate Pokémon.
A room can only have one poster at a time, and its location is fixed. Players can pick which poster is displayed by accessing the room's PC.
One feature of Pokémon Stadium 2 allows players to view the entire room and its decorations, including any posters, in 3-D.
In the third generation of games, there are ten kinds of posters:
- Ball Poster - poster of Poké Ball - 1000
- Blue Poster - poster of Mudkip - 1000

In the anime
A Sea Poster was one of the decorations seen in Keanu's secret base in A Three Team Scheme!. It was one of the few items in his base that was not destroyed by Team Magma when they forcibly took the base from Team Rocket.
