Woodtock,
During World War II, War Bonds were government-issued securities used by the United States government to finance the war effort. They generated funds and made U.S. citizens feel that they were doing their part to support their friends and family members who were overseas in the military. Many organizations, Johnson & Johnson included, held War Bonds drives during the 1940s to get employees to buy the bonds. During that time, many citizens considered it to be their patriotic duty to participate in War Bond Drives.
Hope that helps explain them!
