In case you come back (sometimes rules are meant to protect the person running the forum, so posting links to copyrighted sites is a no-no, here, and where they let you do it), as Dave said it's a filtered look made to look like old film.
If it's still available for free, download Perfect Effects 8, there's likely something in there to do it. Google's Nik Collection will reproduce it in Color Efex 4 and Analog Efex. And I suspect there are a plethora of "Film Presets" available for Lightroom. In fact, the Aged Photo preset that comes with Lightroom is a starting point from which you can likely tweek and save your own.
