This collection of military posters from 1918-1945 focuses on STD prevention. Our grandfather's served bravely for our country, and the last thing anybody wanted to see happen was for these boys to return home after defeating the Axis only to have their pricks fall off because they were celebrating in a bad piece of cooz. Hit the thumbs to check out this ridiculous collection of military STD posters from the early 20th century. [Retronaut]
