We received a donated Nomadic Instand curved display back wall several years ago. We used it one time and have been storing it. The picture is a bit deceiving since the display is just plain black felt. You can hang posters using Velcro. This item is 8 feet wide and almost 8 feet tall. We have the red storage box for the unit to store it compactly. We also have two black halogen lights that can be hung to highlight the display.
Not sure how old this display is, but it is very similar to this current item from the manufacturer
