In our polarized country, it’s important to remember the times when Americans pulled together for a common cause. And when this March 22, 1942 photo was taken, that cause was victory in WWII. Here a cannon off the historic frigate Constitution is inspected. It was sold at auction on Boston Common during Salvage for Victory Day when more than 50 Civil War and World War I cannons were contributed by veterans’ organizations to be sold for scrap.
