Abstract
A device for displaying a document comprises a front transparent planar sheet and a rear planar sheet, each sheet having three edges that are coterminous with and permanently affixed to a corresponding edge of the other sheet, thereby forming an envelope having three sealed edges and an open end; an adhesive strip affixed to either the front sheet or the rear sheet and positioned across the open end between the front and rear sheets to selectively seal the open end; and a protective strip removably affixed to the adhesive strip to prevent the open end from sealing when the protective strip is in place on the adhesive strip and to enable the open end to be sealed when the protective strip is removed from the adhesive strip. When the protective strip is removed from the adhesive strip and the open end is sealed, the device is waterproof.
