Abstract: A readily portable mounting for an adjustable mirror adapted to be positioned over a demonstration area, and capable of convenient adjustment in both elevation and angularity to reflect the upper surface of a support below said mirror towards a viewing audience positioned remotely from said area. The frame for the mirror includes a channel surrounding the latter containing illuminating lamps for effectively casting light on the demonstration area and reflecting the view laterally therefrom. The effectiveness of the apparatus as a demonstration and teaching tool, is enhanced by providing a chalk-board on the mirror frame on the side opposite the mirror, which may be used as an adjunct to complement the visual and/or vocal demonstration or lecture.
