Photographs of 3D objects
Just found a photograph of mine on your site which you claim is public domain. It is a photograph of Michelangelo's Pieta. Photographs of 3D objects (incl. sculptures) are not public domain. If you had just stolen my photo I wouldn't bother (many sites do so), but, with your false designation, you are also misinforming the public and encouraging them to unwittingly steal as well. Could you please remove the photograph from your site? It's this one https://www.wikiart.org/en/michelangelo/pieta-1499.
