This is a 3d model, 1:1 ratio, wearable replica of the Deathstroke helmet worn on by Deathstroke (AKA Slade Wilson). This helmet was modeled after the Deathstroke concept art and statue of David Giraud. This helmet is modeled as the traditional one eyed Deathstroke. This file is available for purchase on my Etsy Account.
