Fifty years later, a man who grew up in suburban Detroit tried to return a very overdue baseball book to his boyhood library, reports AP.

The answer: You can keep it—and no fine

Chuck Hildebrandt, 63, of Chicago said he visited the public library in Warren while in town for Thanksgiving, carrying a book titled “Baseball’s Zaniest Stars.” He had borrowed it in 1974 as a 13-year-old “baseball nut” but never returned it.

But one day he was going through his bookshelf and there was a Dewey decimal library number on the book.

Inside the book was a slip of paper indicating that it was due back at the Warren library on Dec. 4, 1974.

Hildebrandt told AP that he decided to keep the book until 2024—the 50th anniversary—and then try to return it. He figured the library might want to publicize the long overdue exchange.

He said he recently met library director Oksana Urban, who listened to his pitch. Hildebrandt said he hasn’t heard anything since then, though Urban told the Detroit Free Press that all is forgiven.
