Up here in the local region, we have this gal who went to a flea-market and bought an old painting, that had a nifty frame. She was going to toss the picture, but noted that it had a Renoir signature on it, and asked someone to appraise it. It's an original Renoir, and valued at $75k. The lady bought it for $7. It's a great story. But it's mostly bogus.
Here in...lies the story.
This painting had been in a museum over in Baltimore until the late 1950s....then came up missing. Stolen. No leads. An insurance company would eventually pay-off the owner.
Things were believable about the gal's flea-market story except one thing. Her mom was a big-name art instructor, and painter. She was very famous for making fake Renoir copies. This gal who bought the Renoir has continually said she's no expert in art.....but that story just isn't panning out well.
So the FBI is into the mess. My humble guess is that mom picked up the picture one evening and walked out the front door of the building, and simply kept it in a private office of hers for the decades that followed. Both mom and daughter can probably use the cash from the sale. But the insurance company claims that they should now be the rightful owners of the art piece.
