Abstract
A device for displaying and exchanging a plurality of documents of various shapes and sizes and for organizing the same. The device of the present invention comprises at least two layers of pliable sheet material. If multiple sheets are used, the sheets may be nested together. The sheets may then be inserted into a binder mechanism where the binder mechanism compressibly engages the layers to create a pressure region adjacent thereto. The frictional force between the sheet material and the inserted document retains a document inserted into the pressure region formed between two adjacent layers.
