A decorative and functional fixture, which is capable of functioning as a sheetlike object hanger for vertically holding sheetlike objects, includes a front fixture having a substantially flat supporting surface at a rear side, wherein at least a rail groove is vertically extended on the supporting surface; at least a holding ball, which is rotatably disposed in the respective rail groove; and a rear supporting panel, which is integrally connected to the rear side of the front fixture, having a front holding surface extending behind the rail groove and the supporting surface to define a holding gap between the front holding surface and the supporting surface means and a back surface for mounting the rear supporting panel onto a vertical or slanted supporting surface. Whereby, the holding ball will move upward and inward into the rail groove when a sheetlike object is slidably placed up and into the holding gap. Due to gravity, the holding ball will return to its normally rest position again, i. e.
