What makes this artwork -created on a real STOP sign- unique are not only the bullet holes, but also the transparent UV ink the artist used in strategic places: by pointing an ultraviolet light on the sign, you'll suddenly see the zombie's eyes glow, as well as some handprints.
 
Aj Roi used his hands to spread the ink on the sign as if he were a survivor with bloodstained hands desperately trying to climb it to escape the zombies.
 
In his imagination, this sign "lives" on the streets during a zombie pandemic, which is why he personally enriched it with gunshots and pistol shots from various angles.
 
The weapons he used are: the famous AK-47 assault rifle, a shotgun, and a pistol (7.62x39, 12 gauge, and 9mm, respectively).
