This poster is in

 Very Good to Fine condition and is Linenbacked.

The poster looks very good and I believe most collectors would be happy to display it on their wall, but you be the judge from the picture above.

Prior to Linen-backing: The poster was never folded. It was in excellent condition prior to linenbacking. The poster was well backed, and looks great and displays well.

Linen-backing is used to preserve movie posters which makes the movie poster much easier to display.  Linenbacking adds to the value of the movie poster and makes the quality more visible.
