Strange Figures on the Balcony

Photo date: June 13, 2016. Photographer: Mark Mahin.

The photo below shows the West Balcony of Grand Central Terminal, where I have long photographed anomalous-looking sights while photographing from the East Balcony of the station. In this photo we seem to see some strange shadow-like figures. But in the middle we seem to see what looks like some strange creature with a single big eye.

What is very strange here is that the steps look perfectly sharp, but the "shadow men" look so blurry.
