A full-height graphic banner advertising a "Pokémon Pin TRADING WELCOME" event is prominently displayed on a door or partition within an indoor public facility. The banner features a light purple background patterned with numerous small Pikachu head silhouettes in its upper section, with the blue "Pokémon Pin TRADING" logo containing two Poké Ball icons, and the word "WELCOME" in blue capital letters below. The lower section of the banner has a white background adorned with various colored star shapes, depicting cartoon illustrations of a brown Eevee positioned above a yellow Pikachu. The copyright "©2026 Pokémon" is printed at the bottom right of the banner. The banner is situated between a white cylindrical pillar on the left and a glass panel or door on the right. The foreground floor consists of light grey square tiles. Through the glass on the right, an upward-moving escalator is visible, and above it, illuminated red lettering spells out "Rooms 1". Further through the glass, a dark grey patterned floor is visible, along with some spherical orange decorative elements. In the distant background, to the left of the banner and pillar, a lone individual in dark clothing is partially visible, walking away. This scene is consistent with the internal architecture of the ExCeL London Exhibition Centre, located in the Royal Victoria Dock, London, United Kingdom.
