Dating Wrappers with War Bonds Logo

In World War II War Savings Bonds and Stamps were issue to help support the costs of the war effort. If someone didn’t have the money to buy a war bond then they could buy war stamps and save them up until they had enough to trade them in for a war bond. The bonds were named Liberty Bond during World War I, later becoming Defense Bonds; then after the attack of Pearl Harbor in 1941 they were renamed again to just War Bonds. The campaign to sale war bonds was called the Victory War Bonds campaign and ran from 1941 to January of 1946. Almost every company in the US used the War Bonds theme in their ads and on their products.
 

So if you have a candy wrapper or product label with a “Keep Buying War Savings Bonds and Stamps” logo on it then it’s from at least 1941 and up until 1946; also it could possibly be through 1947 since they would use up what was printed before removing the logo and changing the design.
