A sign post support system can include a central column and a plurality of arms extending outward from the central column, the central column configured to support a bottom end of a sign post. A sign post support system can include a plurality of arms coupled to a bottom end of a sign post. A sign post support system can support a sign post without either the sign post or the support system extending below ground level.

A crime scene evidence marker includes a base with a central portion and a plurality of coplanar legs extending in spaced relation from the central portion. A projection is connected to the central portion of the base. A post is removably connected with the projection. The post extends vertically and has an opening in a lower end which is configured to complement the configuration of the projection. The post lower end receives the projection in a mating configuration to removably connect the post with the base. The legs and post have measuring indicia placed thereon.

A surface decoration device and method for decorating a surface with sports related indicia includes a tile including a top surface, a bottom surface, and a perimeter edge. A sports related indicia is positioned on the top surface of the tile and displays indicia corresponding to a sports team. A fastener is mounted to the tile and fastens the tile to a floor surface.

The present invention provides a device for displaying hazard indicia, having a stanchion defining a first end and a second end, whereby the first end defines a first cross section that is smaller than a second cross section of the second end; a base adapted to removably receive the second end of the stanchion so as to maintain the stanchion in a vertical position; and a means for allowing the device to be collinearly stacked on top of a second device such that only the second end of the device and the second end of the second device contact.

An informational plaque mounting system includes a support bracket including a base having a rear side and a front side, and at least one first pivot component at the front side; an informational plaque including a plaque front side and a plaque rear side, and at least one second pivot component at the plaque rear side; wherein the at least one second pivot component is matingly engageable with the at least one first pivot component such that the informational plaque is supported on the support bracket and pivotable relative to the support bracket for varying an angular orientation of the informational plaque relative to the support bracket.

Sign and display systems including a faceplate, lens, backing plate, and at least one magnet are described. In some embodiments, the faceplate includes a viewing aperture and the back of the faceplate includes a recess in which the at least one magnet is mounted. The recess in the faceplate is configured to receive the lens and backing plate. In some embodiments, the faceplate includes two recesses in the back surface, where the first level recess is configured to receive a backing plate and the second lower level recess is configured to receive the lens. The at least one magnet can be mounted in either a first recessed surface of the first level recess or the backing plate. When the lens and backing plate are positioned in the faceplate, the one or more magnets exert a force to secure the faceplate, lens, and backing plate together.
