Drawings of Boys with Gas Masks - A Grim Appearance
Gas masks are designed to protect the wearer from inhaling poison or other dangerous chemical vapor. They’re quite rare to see in day-to-day life, and so they tend to seem quite inhuman and grim… which can add a dash of coolness to a character.
When might your favorite characters wear a gas mask?
