Abstract: A vertical wall support unit includes laterally spaced support members including interlocking means to receive thin box-like receptacles which are open at the top for storage of paper and the like. The thin receptacles are arranged in a vertical, stacked row in overlapping face-to-face relationship with releasable interlocking elements. The wall support unit is constructed with a wedge-shaped portion to tilt the receptacles outwardly and increase the visibility and accessibility of the open tops. Each receptacle in the row engages and is supported by the adjacent receptacle of the row to be held thereby in the desired outwardly tilted position.
