ABSTRACT:
A support for use in conjunction with self-coiling indicia-carrying sheets in a movable indicia display utilizes two identical backing members, and two identical end members, a total of only four parts. Sheet metal is used, and roll retainers are integrally formed on the backing members, as are intermediate edge guides for the indicia-carrying sheets. The end members serve as edge guides, and also provide support for the ends of the roll retainers. The entire assembly is fastener-free, cooperating tabs and slots being used to secure the parts together. In a modified version, each end member is permanently secured to one of the backing members so that the support comprises only two separable parts, which are identical to each other. In another modification, adapted to be viewed from only one side, only one backing member is used.
