An Orb Mans the Information Desk

Photo date: May 24, 2015. Photographer: Mark Mahin.

The photo below was taken in Grand Central Station in New York. We see a large orb at the top right corner. But there is also another orb to be found -- at the corner information desk.

Here is a closeup of the corner window.  We see what looks like an orb behind a window, with the top half of the orb seemingly cut off by the lower part of the window.
