A Victory Garden Inside A London Bomb Crater, 1943

Wikipedia:

Victory gardens, or sometimes known as war gardens, were vegetable, fruit and herb gardens planted at private residences and public parks in the United States, United Kingdom, Canada and Germany during World War I and World War II. They were used along with food stamps to reduce pressure on the public food supply. Around one-third of the vegetables produced by the United States were from victory gardens. In addition to indirectly aiding the war effort these gardens were also considered a civil morale booster — in that gardeners could feel empowered by their contribution of labor and rewarded by the produce grown. This made victory gardens become a part of daily life on the home front.
