Abstract
A holder for stiffly flexible sheets such as flooring samples which are likely to curl at their edges and corners. The holder has a proximal edge, a distal edge, and two side edges connecting the proximal and distal edges. The edges form a top central opening through which a sheet in the holder can be seen. Each of the four edges has a top rail to restrain the sheet from upward movement. The proximal edge has a bottom restraint and an edge restraint to restrain the sheet at that edge. A bottom support extends across the area bounded by the edges to give underlying support to the sheet. The top rail at the distal edge is shaped concavely to form a deflector to deflect the leading edge of a sheet inserted into the holder. Mounting pins can be provided for mounting the holder to a stand. The deflector deflects the leading edge of the sheet which it confronts into a channel. Mounting pins can be provided for mounting the holder to the stand.
