Through rain, snow, sleet and hail, the U.S. Postal Service promises safe delivery of mail to millions of customers across the country.
Even when that mail is more than half a century late.
It's a promise Vienna resident Scott McMurray saw first hand this week, when he received a postcard sent to him by his mother in 1957.
ABC7 reports McMurray's mother, Isabel, and her husband were on a trip to Chicago and sent McMurray, then a teen in Decatur, Ga., a postcard from Shedd Aquarium.
The stamp was marked 2 cents, according to ABC.
The postcard was received in early April in Daytona Beach, Fla. The recipients tracked down McMurray in Vienna to deliver it.
A retired historian, McMurray told ABC he was happy the postcard finally found its intended owner.
It's not clear what caused the delay.
