Abstract: A cosmetic and observer line of sight mirror which includes a mirror having two sets of orthogonal lines with one set substantially horizontal and disposed over the face of the mirror or about the edge thereof to facilitate application of cosmetics to produce a balanced effect and enable movement of the mirror through selected angles about a horizontal axis to afford the user an image corresponding to the user's appearance observed by another at a selected distance and elevation. The mirror may also be provided with supporting means for leveling the mirror and include a scale calibrated in terms of elevation and distance of an observer.
