Abstract: The present invention provides a support for quickly and securely mounting substantially planar objects between substantially opposed surfaces with minimal modification or alteration of said surfaces. The supports of the present invention use the object to be mounted, itself, as a source of pressure which is directed against the mounting surfaces to wedge the substantially planar object between opposed surfaces. The supports of the present invention securely mount a substantially planar object between substantially opposed surfaces without the need for penetration or other alteration of the mounting surfaces using nails, screws, or similar objects. The supports can be used to mount an object permanently or temporarily, as desired.
