Abstract
A poster display device for holding and displaying posters and advertising materials, particular in outdoor environments. A plurality of frame sections are positioned around the periphery of a backing member. The frame sections have rotating cover members which are biased by resilient members to be held in open and closed positions. A transparent protective sheet member is used to cover and protect the poster and advertising materials, and a sealing member is utilized to seal around the edges of the protective sheet member and prevent moisture and other environmental elements from coming into contact with the advertising materials and posters. The sealing members are positioned in slots, recesses, or channels in the frame sections and the force of the resilient members on the cover members holds the protective sheet materials tightly in place against the sealing members.
