[Original HD object](https://skfb.ly/KsHn) (292k verts) from MGD Films.  This is my first test to develop an efficient workflow to "vandalize" existing scans, by baking new textures onto the already baked model (~500 verts). The final idea being to seamlessly vandalize famous buildings with famous paintings. This particuliar object was remeshed with mmgs followed by heavy decimate modifiers in blender. I did not care at all about topology. Baking from diffuse and normals only, using a plane with the Banksy texture as an emission shader.
