ABSTRACT:
A display device is disclosed herein having a base defining a display area between the opposite surfaces of a pair of plates in which a member is magnetically supported on a filament extending between one plate and the member which a magnetic is mounted on the other plate. Magnetic material or a second magnetic is carried on the member in attractive relationship to the first magnetic so that the member is magnetically suspended in the display area pulling taut against the filament. Articles to be displayed such as photos or the like are mounted for visual observation on the member.
