Abstract: An advertising campaign comprises a billboard, and one or more advertising or promotional elements. The billboard is adapted to be positioned along an outwardly facing set of doors in a bathroom facility having a set of partitioned stalls. Preferably, the billboard is sized such that an image or other content displayed on the billboard overlays at least first and second of the doors in adjacent partitions. Each of such doors also includes an advertising or promotional element on its inside portion, i.e. the portion of the door that is viewable from the inside when a person is inside the stall. The advertising or promotional element located within the stall (preferably on the inside door surface) is directly related to (or associated with) the billboard campaign such that outwardly-exposed billboard and the inwardly-facing door panel comprise an integrated campaign.
