One day while walking through a narrow street in Rome, I looked into the workshop of master violin maker, Michel Eggimann. The shop was closed and the latticed window was broken, but I did see a poster of Mona Lisa holding a violin. I also saw the reflection of a doorway across the street. It almost seems like the poster hanging inside the workshop is attached to the reflected door from across the street. :o)
The Mona Lisa poster is not a reflection.
The doorway and wall are reflected.
