A two-part media support housing (321, 322) for use with a barrier system (1') having a foldable barrier arm (31), which is movable to control access past the barrier system is described. The foldable barrier arm (31) includes a plurality of elongate sections, which are aligned in a closed position of the barrier system (1') and extend in different directions in an open configuration. Each part of the two-part media support housing (321,322) is arranged to support a removable media (34) to be displayed and to be mounted to a different section of the barrier arm (31), wherein both parts are arranged in combination to appear to provide a substantially continuous media presentation area in a viewing direction to a viewer of the removable media (34), when the barrier arm (31) is in a closed configuration.
