A wall mountable mirror includes an enclosure and a replaceable film sheet allowing easy repair to commercial bathroom mirrors following vandalism. The enclosure includes a backing frame and a face frame. The backing frame is mounted to a wall and the face frame is connected to the backing frame by two pairs of parallel links. A top link pair is preferably longer than a bottom link pair. The film sheet includes small edge rods attached along each edge. The face is pulled out and down to open the enclosure to replace the film sheet. When the face is closed, the last closing motion provided by the links is a parallel motion which uniformly stretches the film sheet by pushing the edge rods over corresponding curved tensioning members to stretch the film sheet providing uniform stretching in two dimensions to provide a flat reflecting surface.
