This is an original production used shooting script for A New Hope.
The diference what makes this a shooting script, is the colored pages, this one has mostly pink color, and about 20 in the middle are blue, and one is yellow. That color codes mean revisions made into the script by the time of the shooting or filming.
Once the filming has ended, they usually edit again the script into white pages, for other departments, with all the revisions on it.
