It is in great shape, unused and handled infrequently. Please look at the photos and judge the condition based on those. Because it is a tri-fold the poster is in better shape than most that were fully folded. It is very "white" and not yellowed. There is no "hair" on lukes belt.
The paper quality is consistent with an original. The identifiers for a reproduction are not there. I have several examples and this poster matches all logos, paper quality, and has does not have repro'tells.
