Abstract: A holder for planar material includes a first panel and a second panel hingedly connected to the first panel. A prong is secured to the first panel and extends in a direction approximately normal thereto. The prong has a pointed tip. An aperture is defined in the second panel. The pointed tip pierces an associated planar material located between the panels such that the prong of the first panel can pass through the associated planar material and enter the aperture of the second panel when the first panel overlies a portion of the second panel, thereby holding the associated planar material between the first and second panels. A clip is connected to at least one of the first and second panels. The clip allows the holder to be mounted to an associated support.
