<p>The poster fastening system consists of a surround made from retaining members (31) with studs (211) to engage with perforations in the edges of a poster, and fasteners (41) to fix the retaining members to upper and lower cross-pieces (21) of a frame on the supporting surface (1). The components of the system can be made e.g. by moulding and/or extrusion from aluminium, metal alloy or composition material.</p> |
