Flynn's Dictionary of the Underworld

In 1925, Flynn's magazine published the groundbreaking "Dictionary of the Underworld" with over 2,200 slang words and idioms used by crooks, hoboes, and grifters. The series decoded the language of the underworld, covering crime and criminals of all kinds, along with topics such as prisons, money, and drugs.

Long cited as a vital source for early 20th-century slang, this rare collection is now presented as a single new compilation with annotations, offering readers a fascinating glimpse into the language of America's criminal past.
