Abstract: A tamper-resistant display holder is responsive to the selective application of an external magnetic field. The display holder includes at least one frame section having an elongated front member and an elongated back member which are adapted to be interconnected to one another in a pivotal relationship for holding a display piece. The display holder further includes a magnetically attractable locking tab having first and second opposite ends. The first end is pivotally attached to the front member such that the second end is movable between a locked position and an unlocked position relative to the back member in response to the external magnetic field.
