PAULS VALLEY, Oklahoma - Bert Jacobson says he still has faith in the U.S. Postal service, even if it took 46 years for his postcard to arrive.

On Friday a postcard he sent back home to his mother in Pauls Valley in January of 1967 finally arrived.

"Under a piece of machinery? I don't know. I have no idea," says Jacobson about why it took so long to deliver the letter.

Bert sent the postcard on a trip with his father and cousins to the east coast to buy concrete trucks and mixing equipment for the family business.

"It was an awesome trip," Jacobson remembers.

The postcard from the Old Country Store Museum in Hereford, Pennsylvania has a 1967 postmark, a 4-cent Abe Lincoln stamp and Jacobson's message to his mom.

"Mom, Hi. We've been having a great time," Jacobson reads from the post card he wrote as a 13 year old.

"She wasn't surprised that Bert had written her a card, but she was very surprised to took 46 years to get here," says Marilyn Hubbard, Bert's sister, about their mother's reaction to the card.

Bert addressed the postcard to the same P.O. box the family's concrete business uses today in Pauls Valley.

"I'm sure this is one in billion. Mine just happened to be one of them," adds Jacobson.
