Vintage NOS Star Wars Movie Poster 1982 Lucasfilm No folds tape or holes RARE

Vintage NOS Star Wars Movie Poster 1982 Lucasfilm No folds No tape No holes. Been up in closet since parents bought for us as kids. The plastic around it was spent and dusty. Had to make sure poster was okay. Last three pics show flaws/indentions but were there because I flattened with large piece of cardboard.

Not sure if its common with these posters. Measures 20 inches wide by almost 28 inches long.
