Corner mounts are a very understated way of displaying your menu. Paper is held in place by four small corner pockets on the inside front and inside back of the menu covers. You can display four or six sides retrospectively by adding extra hinges to the inside of the spine, or by using a wing and interscrew if you wish the pages to be removable.
Opaque acetate sheets are also available if desired for protection against potential marks and spillages to your menu cards.
