The Prohibition era of the 1920s left an indelible mark in American history. Temple historian Bryant Simon used an old political cartoon to help explain the era. The cartoon "shows a picture of a series of wooden barrels of booze containers walking down the street," he said. "What's interesting is that they're holding signs and none of these signs are about moral reform. They're all about the way in which booze creates disorder. Prohibition, to my way of thinking, is not very much about moral reform but about political and economic reform and reforming the product of industrial society — workers themselves."
