One of the most famous sayings from World War II posters is the phrase "Loose Lips Sink Ships" that originated with this poster. Although the poster includes the word "might" the phrase is remembered without it.
The poster was issued in 1942 by the House of Seagram (Seagram Distillers) of Montreal, Canada, one of a series created for use in taverns. At the bottom, the poster has text reading, "This Poster is Published by the House of Seagram as part of its contribution to the National Victory Effort". The artist, Seymour Goff, signs as Ess-ar-gee.
