Have you ever read about Van Gogh or Picasso paintings discovery worth millions? Well, I believe this type of findings can be done in a places like this.
Unfortunately I am not an expert in those type of knowledge, so no luck for me. But a keen art nose just might find something valuable here. Or at least to put on the wall and make a better home.
The gallery on the photo was found in an Istria, Croatia. And I made a quick photo with my iphone.
