During World War II there was a campaign to encourage the use of homegrown foods. Because commercially canned goods were rationed, the Victory Garden became an indispensable source of food for the home front. The Victory Garden was a household activity during the war and one of the most well received of all home front chores. At its peak, it is estimated that nearly 20 million gardens were grown and about 40 percent of all vegetables produced in the U.S. came from Victory Gardens.

Across the nation, home canning and preserving of farm produce flourished so that more supplies would be made available for our troops. The idea was simple in conception and inexpensive for the individual American at home to carry out. Of all the advertising techniques used to make Americans feel a part of the war effort, propaganda posters were perhaps the most successful.
