An individual sheet display module includes a frame assembly for framing and retaining a sheet within the module, and complementary first connectors (tongues) and second connectors (grooves), attached to opposite sides of the module, for connecting adjacent modules to each other to form a page in the album. The album binder assembly supports the plurality of sheet display modules in album form. The album binder assembly includes a spine element and a support assembly, connected to the spine element, for supporting a plurality of module support bars. The module support bars include apertures for connecting the module support bars to the support assembly and which also include third connectors on the support bars which are complementary to the first connectors, for connecting the support bars to the first connectors on the display modules.
