Prohibition was more popular in rural areas than in cities, which saw a proliferation of secret saloons and nightclubs called “speakeasies.” The exact origin of the term is unknown, but it may have come from the need for prospective patrons seeking entry to whisper—or “speak easy”—through peepholes in the front doors of the illegal establishment, such as the one in this photograph from the 1930s.

Moonshiners working outdoors in rural areas of the country devised a clever method to cover their tracks—literally. In order to evade Prohibition agents, moonshiners attached to their shoes wooden blocks carved to resemble cow hooves. That way, any footprints left behind would appear to be bovine, not human, and not attract suspicion. This photograph shows one such “cow shoe” seized by the police.

Americans who continued to consume alcohol during Prohibition had to find creative ways to hide their booze. In this photograph, a woman demonstrates a faux book that was used to conceal a liquor flask.

As this 1932 photograph shows, home furnishings such as lamps were also adapted into hiding spots for alcohol bottles.

The left side of this 1928 image depicts a woman wearing a large overcoat that would attract no notice. When the overcoat is removed for the image on the right, it reveals the woman has strapped to her thighs two large tins used for transporting alcohol.

Some wily drinkers even incorporated their secret hooch hiding spots into their fashion sense. This 1922 portrait depicts a woman seated at a Washington, D.C., soda fountain table, as she pours alcohol from her cane into a cup.

The Treasury Department initially had the responsibility for enforcing Prohibition before it was transferred to the Justice Department. In this photograph, law enforcement agents examine a trove of 191 pint bottles that were discovered hidden underneath a sailor’s mattress on a steamer that docked in Norfolk, Virginia.

The illegal manufacturing and sale of liquor, known as “bootlegging,” occurred on a large scale across the United States. Bootleggers relied on creative ways to hide their shipments. This 1926 photograph taken in Los Angeles shows what appeared to be a truckload of lumber. When federal agents approached the vehicle, however, they smelled the odor of alcohol and discovered a cleverly concealed trapdoor that led to the interior in which 70 cases of prime scotch were hidden.

Bootleggers sometimes ran extensive operations out of their houses. This 1930 photograph shows policemen examining liquor bottles after a raid on the Long Beach, New York, home of Eugene Shine. Inside they discovered $20,000 worth of booze.
