The "Astonishing Legends" guys did a six part, fifteen hour deep dive on Patterson-Gimlin. One of the segments presented "experts" in costume design, period photography/cameras, and actors who make/have made a living performing in costumes as monsters, animals, etc. To the AL guys' credit, they got "experts" who espoused opposite views on the film. The Morris claims figured prominently. The one line I remember was a costume designer who referred to "Patty" as a "bad monkey suit."just like the sites that grab the art contest pics and claim them to be real....or the patterson/gimlin film....morris costumes claim that they made the suit for patterson...that claim is even on their website....lol.... but people are gonna believe what they want.
I agree with you about various sources scrounging up unrelated photos/illustrations for articles. I notice it mostly with UFO stories, either because I know the provenance of the illustration or because it bears no resemblance to what was claimed to have been seen.
