Abstract: An optionally extending or retracting display panel assembly, comprising a horizontally elongated support bracket configured for support at an upper portion of a relatively large first container, or the like, primary magnetic apparatus carried to magnetically attract the bracket toward the container, for removable bracket attachment to the container, and the display panel assembly and associated connections configured for horizontal displacement guiding by the bracket during panel extension and retraction relative to the container, while the panel remains generally vertically proximate a vertical side of the container. A counter-weight system assists panel leveling as well as extension and retraction.
