Endless Paradigm

Does anyone know if it's possible to get satellite images from the 1990s, either from Google Maps or anywhere else.
I remember a number of years ago, someone had used satellite images from the 1980s and compared it to images from the current of the same locations. This was for a school project. I'm not sure how they got it, and I can't find anything of that sort on Google Maps (but maybe I'm not looking hard enough).

Thanks.

well im sure its possible, google earth has a setting for that

I've got some satellite images if you need.
