ABSTRACT:
A cold air inflatable screen which can be inflated with a suitable air source and has sidewalls and a backwall and top and bottom and a front screen of white material. The screen is inflated and is tied down with suitable tie lines and a projector is placed inside the screen for projecting advertising or other material onto the white screen. Zippers are located in various locations so as to allow the balloon to be deflated. Thus, the inflatable screen or balloon can be moved rapidly and assembled in a new location for furnishing messages or other material.
