Abstract: A door sign includes spaced front and rear panels with a side panel perpendicularly disposed therebetween. Both the front and rear panels each include an angularly extending slot for accommodating a door knob shaft. The side panel includes an elongated opening for receiving the door knob latch and possibly a dead bolt latch if the door is so equipped. The sign is positioned such that the door knob shafts are within the angular slots and the door knob latch is protruding through the side panel opening. If the door is closed and locked, the sign cannot be removed without unlocking and opening the door thereby preventing tampering or removal by unauthorized passers by.

Abstract: A magnifying insert designed particularly for a binder having separable binding members for securing pages of printed material therein includes a substantially rectangular panel having a pair of side edges, a top edge and a bottom edge. The panel is a Fresnel lens for magnifying small or unreadable indicia on the pages secured within the binder. Along an edge of the panel are a plurality of apertures, each spaced, dimensioned and positioned to receive a select binding member. The panel can be interchangeably used as a conventional insert, a divider, a page mark or as a magnifying lens for enlarging fine print appearing on the bound pages. The panel can also include measurement indicia along an edge thereof allowing the device to also function as a measuring tool.
