The Green Bag was a popular legal magazine published in Boston between 1889 and 1914—the Progressive Era—containing news of legal events, biographies, and essays, generally in a lighthearted tone. The magazine was initially captioned "A Useless, but Entertaining Magazine For Lawyers"; later "An Entertaining Magazine for Lawyers". The name of the magazine was purported to reflect the use of green bags by barristers, although this assertion was disputed.
