@FeralRobots @RickiTarr I did a reverse-image search and of the websites that turned up, were still functional, and weren't imgur, I found a tumblr blog for someone's 70s food book, which is not a cookbook but just photos of food and some sarcasm. It's *possible* this was made at one point but I think the origin is lost if it was. Given that the book wasn't well-researched, I doubt the photo was staged, though.
That strand is banana skin, though, rather than parsley stem.
