  • London Underground advertising in the United Kingdom: Liberty posters reading A gift less ordinary line the wall beside an escalator.

    Escalator Panels

    Escalator Panels in Seoul are booked around Gangnam, Myeongdong and the subway network. We use them when the campaign needs that specific job: scale on a landmark face, or frequency on a route people already take.

    Escalator panel advertising in Seoul is one of the few outdoor surfaces that can run a sequence. The ride is slow and the sightline is fixed, so a story can unfold between street and platform.

  • London Underground platform advertising: a long Ripple poster along the tunnel wall reads Progress is worth more than promises, as a red train arrives.

    Posters

    Posters in Seoul are booked around Gangnam, Myeongdong and the subway network. We use them when the campaign needs that specific job: scale on a landmark face, or frequency on a route people already take.

    Poster advertising in Seoul scales from a 4-sheet in a corridor to a 96-sheet across the tracks. A single campaign can cover intimate station sites and landmark cross-track positions together.

    Station domination in Seoul makes the commute the campaign. Entrance, escalators, platforms and gates are planned as one sequence, so the station itself carries the brand.
