Most movie posters, printed up to 1990 were folded before being shipped to theaters. So, most of the posters that presented by turkposter.com, are originally folded.

Cause of that reason, i dont use MINT Condition for a poster, even it isn't used.

EXCELLENT Condition means , the poster isn't used, no any faults except originally folded.

VERY GOOD Condition means, the poster may have slightest of wear, slight wrinkles, short border tears.

GOOD Condition means, the poster may have minimal wear, possible pinholes, slight fold wear, minor tears or slight marks & yellowing.
This kind of posters will be noticed about it's faults.

Sure, the condition gradiant of a movie poster makes differances about it's price.
