A violin, bought as a fake, with this obviously fraudulent label. The violin looks like it’s from the same town that the label indicates, but it certainly isn’t as old as the label says:
Notice how the label isn’t glued in all that well, though. It’s in the wrong place, near the center of the back, looks hastily slapped on, and is a bit loose around the edges. What do we see when we take a look underneath? A signature of the real maker!
Somewhere along the line, someone thought they’d upgrade the violin, but contrary to their intention they downgraded it by turning it from a signed original into an obvious fake. The real maker is obscure, but he’s a known maker, and now the violin is real again, with the real maker’s name attached. That’s a solid upgrade.
