A display frame, which carries a sheet of mylar metalized to provide a mirror and an advertising display placard, is provided with a number of straps disposed for coaction with a turnbuckle type mounting device to securely position the display upon pillars of I-beam configuration such as those found in subway and train stations. The turnbuckle assembly of the mounting device is such as to exert compressive forces against opposed inner faces of the I-beam flanges and, in one embodiment, coacts with straps secured to the rear wall of the display to mount the display across the edges of said I-beam flanges so as to hide the mounting means in the space behind the display and between the flanges and web of the I-beam pillar. The display frame is formed with one or more advertising placard mounting sections formed with grooves to facilitate positioning and easy removal of the placards which carry an advertising message. Such display sections in some embodiments are at an angle with respect to the mirror. A fluorescent lighting fixture, carried by some embodiments of display frames, is disposed behind the placard display section and for translucent placards to provide a back-light for the message.
