'The Butler' -- Priceless Script Signed by Oprah STOLEN

A precious script from "The Butler" -- signed by Oprah and the rest of the cast -- has been stolen ... and cops think it could turn up at an L.A. sale.

Co-producer David Jacobson came home recently to find his doors flung wide open, his Hollywood house ransacked and his car missing. A frantic Jacobson searched inside and quickly noticed one of the pilfered items was the prized script.

Cops determined Jacobson was hit by a burglar who had broken into other homes in the area.

We're told 2 other victims found some of their stolen property at a nearby garage sale. Cops talked to the people who were running the sale and the guy told them who gave him the stuff to sell.
