An apparatus (10) and method for creating real image illusions utilizes a partially transparent scrim (44) positioned between the real image (16) and an optical system (14) which produces the real image (16) from a corresponding real object (12). When the scrim (44) is illuminated by a light source (54) or projector (58) in front of and at an oblique angle to the scrim (44), the scrim (44) forms a seemingly solid and non-transparent surface that conceals the optical system (14) from view by an observer (42). The scrim (44) also protects the optical system (14) from damage and other vandalism, yet it does not distort or interfere with the light rays (26) passing through the scrim to form the real image (16). The scrim (44) also avoids distracting surface reflections, ghosting and other highlights.
