Q:I have a beer poster that seems quite old. It pictures a nymph sitting next to a bottle of Schlitz beer. The label on the bottle says it is less than 1/2 percent alcohol. How old is this poster?

A:Your poster was probably made during Prohibition, between 1919 and 1933. A picture of a nymph might indicate it was made during the early years of Prohibition. The Volstead Act, or National Prohibition Act, was passed on Oct. 28, 1919, and prohibited the sale of intoxicating beverages. Beer that had less than 1/2 percent alcohol by weight was considered non-alcoholic and was allowed. Schlitz was one of the brewing companies that made "near beer" or "non-alcoholic" beer. The legal limit of alcohol content was raised to 3.2 percent on April 7, 1933, when the Cullen-Harrison Act was passed. Prohibition was repealed on Dec. 5, 1933. This poster has been reproduced in the last 20 years. If yours is old and large, it's worth hundreds of dollars.
