Abstract: An upright standard is provided including upper and lower relatively telescoped and slidably adjustable end portions. The lower end of the lower end portion includes a horizontally enlarged floor engageable base and the retention structure is operatively connected between the upper and lower end portions for releasably preventing downward movement of the upper end portion relative to the lower end portion from selected extended positions of the upper end portion relative to the lower end portion. The upper end of the upper end portion rotatably supports mirror mounting structure for angular displacement relative to the upper end portion about an upstanding axis and a mirror element supporting frame is supported from the mounting structure for angular adjustment about a horizontal axis generally paralleling the mirror element.
