Advertisement panel

摘要

The panel folds at right angles along two lines so as to form the container. The rear wall of the latter has an extension forming a support for advertising slogans and/or pictures, and whose surface area is roughly equal to that of the wall proper. There can be extensions of the rear wall at its sides and at right angles to it and which form supporting feet. Openings can be provided near the top of the extension for the insertion of suspension hooks.
