These are mug shots from Australia from the 1920’s.
Here are the two main things I see.
1. There is no false bravado that exists amongst the criminal class today. These men don’t need to peacock their masculinity, they’re comfortable in it.
2. There is more class amongst this group of criminals than the vast majority of Westerners. I guarantee you that, even though they didn’t live by society’s rules, these men had their own code of honor and adhered to it.
