Brilliant 1938 Japanese gas attack posters
In 1938 after the Japan-China war, Japanese government and the Red Cross teamed up to create a series of precautionary posters concerning the Anti-Aircraft Defense Law. This law required citizens to be aware of the possibility of gas attacks and the protective measures they should take incase one actually happens. These posters demonstrate proper gas mask-wearing techniques, what to do if gas comes in contact with your skin, and even how to protect your children.
a gas mask, I would be in a far worse mood than the people in these posters.
