The present invention relates to a communication and visual exposition board completely different to the ones already known; to which it is only necessary to place a strip cartridge with the material to be exposed, said strip or roll of flexible material (paper, polyethylene, mill-board, etc.) is held by means of two rollers for the user to rotate in the desired direction so that the material to be exposed passes at the front of said board over a translucent surface, this surface has the quality of being illuminated from within so the user exposing it can carry out its presentation in a tenuous light or in total darkness. Moreover, said board is provided with a transparent surface placed at the front of it, so the strip of flexible material (paper, polyethylene, mill-board, etc.) remains between the translucent and the transparent surfaces, the transparent surface can be or not a rigid or a flexible one; and has the property to write, draw and erase over its both faces. Furthermore, t his transparent surface has the property of housing printed documents so that it is possible to work on them without altering or modifying in any way the exposed document, because what is written, drawn or erased is done over the transparent surface and not over the printed document; therefore, the expositor will have the necessary elements to perform a dynamic, continuous exposition with more clarity and quality.
