The letters shown above are being held by a Colorado women named Amy Lehocky. She wrote the letters — mostly love letters to her then-boyfriend — 19 years ago and dropped them in a decommissioned bank night depository that she mistakenly thought was a mailbox.
The love letters (along with a few other pieces of mail that Amy dropped in the depository) were recently liberated from the depository during some building renovations and were returned to Amy, who then shared them with her long-ago boyfriend, with whom she's still friendly.

(My thanks to Bo Baize for letting me know about this one.)
