Free standing and wall mounted poster and sign displays are disclosed. Each of these devices comprise a sign frame with similar top and bottom curved extrusions, similar side frame extrusion members, and a backing member. The upper and lower frame extrusion members include elongated slots which are used to hold the display indicia in place by the "lift and fall" principle. The side frame members contain spring biased cover members which clamp the sign materials in place against the backing member. A clear protective covering member is hooked in place in the slot in the upper frame extrusion member. Unique corner connecting members are used to secure and connect together the frame members around the backing member forming the sign devices. The corner connecting members comprise cap members which cover the open ends of the upper and lower frame extrusion members, as well as insert members which fit within the open ends of the side frame extrusion members. The free standing sign frame also includes a base assembly comprising a pair of leg members and spring members. The sign frame is attached to the top of the spring members.
