I want to create a fake spokesperson for a line of products I am creating in a specific niche. Is it legal to create a fake person with a name and picture? I also want the person's name to be "Dr. ___" and claim that he/she is an expert. If I don't provide any details about why this person is an "expert" and I don't explain that they have a PhD or anything specific, is this legal? Technically I'm not saying this person has a PhD, I'm just labeling them as "Dr. ___", but I don't know where the legal line is drawn here. I know companies have spokespeople who are characters and not real people, persay, but I don't know what the limit is on this strategy. Any and all input on this thread would be greatly appreciated.
