ABSTRACT:
The holder comprises a base together with an upright central post. The post carries thereon at least one pair of pivot carriers which are separately movable up and down the central post and clamped thereto at selected positions. Each of the pivot carriers has pivoted thereto a pair of arms. The outer ends of the arms are attached to each other by a pivot-carrying clamp. The pivot axes are all parallel so that two triangles lying in the same plane are formed. Paper holders may be attached to the arms at any selected position to display a flat pattern. When two such sets are used together, the flat pattern can be held in a 3-dimensional display.
