Photo: US Postal Service. Pluto - Explored! In 2006, NASA placed a 29-cent 1991 Pluto: Not Yet Explored stamp in the New Horizons spacecraft. In 2015 the spacecraft carried the stamp on its history-making mission to Pluto and beyond.
The 18th Amendment to the U.S. Constitution banned the manufacture, sale, and transportation of alcohol (i.e. the beginning of Prohibition). It was ratified on January 16, 1919 and repealed by the 21st Amendment in 1933.
The numbered amendments usually refer to the changes (additions) made to the Constitution of the United States of America. The 18th Amendment is therefore the 18th change toâ¦ this constitution - I believe this one banned alcohol the prohibition amendment (it was later repealed - (reversed)).
