The NWI Helmet

This strange leather helmet was found in the rooms of Elias Kingsley, nefarious operative of New World Incorporated.

The prop is a modified WWI leather pilot's helmet acquired at an army surplus store. You can see the small mound in the center of the earflap: that is where the left headphone is hidden. You can see the small holes in the ear area on the inside of the helmet, which is where the right headphone is located.
