Museum souvenir card showing two views of the Bureau de Campagne de Napoléon Ier — Napoleon the First's portable campaign desk — photographed against a plain studio background. The left view shows the desk closed as a compact cylindrical mahogany cabinet on tapered legs with a circular lower shelf. The right view shows it open and deployed, with the writing surface extended, a small document tray raised, and the accompanying campaign chair positioned beside it.
