Except there are now so many photos of the crowd surrounding the Mona Lisa [1] that maybe it would be a more productive use of your time to take photos of the people taking photos of the crowds around the Mona Lisa.
Your Google search has such a photo[1], and I actually really like it.
Actually on closer inspection she might just be taking a selfie. Which would also be ironic in a different way, as neither the Mona Lisa itself nor the crowd would be in shot.
I've been there. The people pretending to hold back the leaning tower are more entertaining than the tower itself.
The pose incidentally seems to be some sort of universal human reflex. When we visited there were at least 100 people in the same position while their friends took pictures. They all seemed to be having a good time.
