A Hyper-Real Plague Doctor Mask With Futuristic LED Lights The concept of the Plague Doctor mask is one that has been trapped in cultural consciousness since the plagues of Medieval Europe. This particular mask takes that concept and propels it forward in time with the addition of LED lights and other modern-day styling cues. It’s perfect for cosplay events and costume parties or just a night taking the kids out trick-or-treating after the sun goes down.
