Abstract: A system for advertising, having a post assembly with first and second ends. The first end has a first neck member with a first threaded opening having a cap thereon, and the second end having a second neck member with a second threaded opening. A display assembly has first and second transparent or translucent walls joined at least at first, second, and third edges. The display assembly further has a first seam to define a first channel and a second seam to define a second channel. A fourth edge defines a sealing edge. First and second elongated rods prevent the display assembly from bending or flapping. The display assembly displays matter housed between the first and second transparent or translucent walls. An extension post assembly has third and fourth ends, and at least one tension arm.
