ABSTRACT:
The present invention relates to a sign that can be hung from a suspended ceiling. Specifically, the cantilevered and/or counterbalanced sign rests securely in the inverted "T" rail of a suspended ceiling tile grid, and can easily be inserted or removed without damaging or destroying the ceiling tile. At the same time, the cantilevered and counterbalanced structure of the present sign permits the sign to rest securely on grid rails with varying support ledge designs, shapes and dimensions.
