Hemp for Victory (US dept of Agriculture, 1942)

From http://en.wikipedia.org/wiki/Hemp_for_Victory :

Hemp for Victory is a black-and-white United States government film made during World War II, explaining the uses of hemp, encouraging farmers to grow as much as possible.

The film was made to encourage farmers to grow hemp for the war effort because the United States was facing a hemp shortage. The film shows a history of hemp and hemp products, how hemp is grown, and how hemp processed into rope, cloth, cordage, and other products.

As it was made by the US Government, it is public domain and is freely available for download from the Internet Archive.

Before 1989, the film was relatively unknown, and the United States Department of Agriculture library and the Library of Congress told all interested parties that no such movie was made by the USDA or any branch of the U.S. government. Two VHS copies were recovered and donated to the Library of Congress on May 19, 1989 by Maria Farrow, Carl Packard, and Jack Herer.

The only known copy in 1976 was a 3/4" broadcast quality copy of the film that was originally obtained by William Conde in 1976 from a reporter for the Miami Herald and the Ethiopian Zion Coptic Church of Jamaica. It was given in trust that it would be made available to as many as possible. It was put into the hands of Jack Herer by William Conde during the 1984 OMI (Oregon Marijuana Initiative). The film 20 years later is now available anywhere through the internet.
