Postal workers found an ancient love letter, sent in 1958, at a Pennsylvania mailroom. They're trying to track down the intended recipient. Reuters writes: 'The letter had been addressed to Mr. Clark C. Moore, then a junior at the university, which was known at the time as California State Teachers College, she said. It included a return address, but little other information about the sender, who signed the letter, "Love Forever, Vonnie."' Follow @BoingBoing on Twitter.
