Yes, I think I understood you. A painting can still be a forgery just because it is claimed to be the work of some artist. There doesn't have to be an original. It isn't what it is made out to be. I am cynical about the superiority of no-digital stage. Every so often someone tells me how long ago it was that digital stuff started being used in studios. And I forget. But it's quite a while. They also tell me how tape degrades, leaks, etc etc, and how it is a major job to restore them, let alone use them as a good analogue source. But... Honest description of the goods is the keypoint.
