An individual on Facebook has been screen grabbing historical photos that are sold here on ebay and also when they are presented on Worthpoint. He has been colorizing them and putting them into collages that he then posts to harvest his own "Likes" and comments, etc. We understand he intends to sell them in the future. He does not purchase the photos or even own the photos he has been grabbing from ebay and Worthpoint. Advising any sellers of vintage items to put some watermark of "Do Not Copy" or whatever to prevent this surmised unethical practice.
