Star Wars The Empire Strikes Back Movie Script 1978 READ DESCRIPTION

Description

I do NOT KNOW exactly what this is. I don't think it is a production script as the cover says they were numbered in red. I'm pretty sure this is vintage 1978. I presume a script expert would know and I'm pricing with that in mind.
In good condition. Please examine photos carefully. I am basing my asking price based in research of collectable books and autographs. I am open to fair offers.
Item sold as is but guaranteed as described.
I am selling the contents of an estate of a bookseller whose business was in West Los Angeles. He has hundreds os signed books as a result of 40+ years in business. I do not know the history of the book you're looking at but I have had no problem with any of the many books and autographs I've sold so far. I guaranty all my sales to be as describe to I will take back and fully refund.
