Necco Wafers, its signature product, had been part of Americana since before the Civil War. In fact, the company said the chalky wafers were a favorite of soldiers because the confection didn’t melt, so the sugary treats were consumed by Union soldiers on the battlefields here at home to the European theaters of both World Wars to today’s conflicts in Iraq and Afghanistan.
