Workers at the Trumbull Library are looking for the person who left a pile of vintage family photos between the pages of a book.

The photos were found inside a volume that was donated to the library book sale. They date back to the 1930s, and include portraits, a few baby pictures and one of a calf.

The library director figures since they are so old, they are probably irreplaceable, and someone will be very happy to have them back.

"It's a nice story, there is a flair of mystery to it, there is a whole lot of narratives to it," said Stefan Lyhne-Nielsen, Trumbull Library director.

Volunteers say they often find things in the books donated from the sale, but this is very intriguing to them.

If you recognize these photos, you can call the library.
