Mug shot: A photograph of someone’s face especially one made for police records. The word “mug shots” comes from the British slang word “mug” meaning “face.”
According to a website dedicated to Lucy Parsons:
For almost 70 years, Lucy Parsons fought for the rights of the poor and disenfranchised in the face of an increasingly oppressive industrial economic system. Lucy’s radical activism challenged the racist and sexist sentiment in a time when even radical Americans believed that a woman’s place was in the home.
She was a leading American radical labor organizer and activist with the Industrial Workers of the World (as well as other political organizations). Parsons’ mug shot was taken in Chicago after she was arrested for rioting during an unemployment protest at Hull House in 1915.
