June 25 (UPI) -- A Michigan library received a long-overdue book in the mail along with a letter from the daughter-in-law of the woman who checked it out in the 1940s.
The Ann Arbor District Library said in a Facebook post that the copy of Social Studies in the Public Schools of Ann Arbor, Michigan Grades Three to Six was returned via mail after being about 70 years overdue.
The book was checked out by Mary Rowland Fischer, who worked as an art teacher at Tappan Middle School and Northside Elementary in Ann Arbor until retiring in 1966.
Kari Magill, Fischer's daughter-in-law, mailed the book back to the library along with a letter explaining the overdue tome.
"Please accept this (rather late) overdue book return. Apparently Mary Rowland overlooked the due date. She was a local teacher, preparing to start a family at the time. Perhaps you might consider waiving the fine, as Mary passed away in 1967?" Magill wrote.
The library confirmed in its Facebook post that it would not attempt to collect any fines for the late return.
