We were strolling through Vienna, enjoying the city and all of its history. While you could guess the age of the building around you, the city itself was sparkling clean for the people to enjoy. All of a sudden, there was an angle that caught my attention. There was a window that somehow seemed fascinating to me. I was standing there for quite some time, waiting until somebody would get closer to the glass from the inside. In the end, I never got to see a person, I am sure this picture captures the aura of Mr. or Ms. Invisible.
