A display system comprises one or more display elements in the form of hollow geometrically shaped pillars that can be easily assembled, disassembled, and stored. Each display element is comprised of a plurality of side panels that are removably interconnected in an overlapping manner to themselves and a base. Each side panel has a dense arrangement of mounting apertures formed in at least a portion thereof configured to receive and provide support for mounting hardware to which signage and other elements can be connected. Multiple display elements can be ganged together by themselves or with removably shelving to allow for construction of a wide variety of presentation spaces and structures.
