Patent attributes
A sign holder including a main portion, a flange, and an interface hook. The main portion longitudinally extends in a substantially planar manner and defines a top end, a bottom end opposite the top end, a first surface, and a second surface opposite the first surface. The flange is folded back from the bottom end toward the top end and the first surface of the main portion. The flange is biased toward the first surface of the main portion. The interface hook is folded back from the top end toward the second surface and the bottom end of the main portion and is configured to receive a portion of a shelf assembly to couple the sign holder to the shelf assembly. A pocket is defined between the main panel and the flange and is configured to receive a printed medium. Display systems and methods of use provide additional advantages.
