Abstract: A display frame for supporting an image insert for display is provided. The display frame comprises i) an abutment structure for supporting the image insert for display; ii) an upright member including a first connection member and a second connection member; and iii) an interlocking mechanism for interlocking the first connection member and the second connection member. The upright member has a first substantially planar state and a second non-planar display state, and is operable to support the abutment structure. The interlocking mechanism is operable to interlock the first connection member and the second connection member such that the upright member is in the second non-planar display state.

Abstract: This invention is the addition of a wireless radio link to a real estate lock box to transfer the data obtained from the access keypad to a nearby receiver which sends the data to a central site computer and compiles the data for dissemination. The lock box can also be controlled from a central site via a radio link.
