Thank you for request! Sitting lazily sunday afternoon, I wanted to investigate this subject.
It was searched and found such an image: https://upload.wikimedia.org/wikiped...version%29.png
I was very surprised!
Somehow this doctor must be very unhappy because must show such a strange appearance!
I laughed, so I tried to make such a character sketch.
Spoiler
Probably such a mask is useful for clown tricks. Sorry, it was a lazy sketch.
If you would like to draw something, please show me!
