    # "35mm (and occasionally 16mm) scans of random and occasionally interesting things from the past when cinemas ran actual film.\n\nWe have invested a LOT of time and money into this project and are posting the files WITHOUT a burned-in watermark for those who want to download the videos for their own home private use.  All we ask in return is for everyone to please show professional respect by LINKING to the video on our youtube page instead of re-uploading our videos to your channel or elsewhere on the internet (or selling them on physical media).\n\nPLEASE UNDERSTAND IF OUR WORK IS RE-UPLOADED BY OTHERS OR SOLD ON PHYSICAL MEDIA TO PASS IT OFF AS THEIR OWN, WE WILL HAVE NO OPTION BUT TO WATERMARK OUR FUTURE VIDEOS OR TAKE OTHER ACTION.\n\n100% of the content on this channel was scanned and restored by us from original film elements.  If you are in need of professional film scanning services, please email us at the business inquiries email below.  \n\nThank you for your support.",
