This is a vintage edition of the Nancy Drew Mystery, The Clue of the Tapping Heels by Carolyn Keene (#16). 1980s flashlight edition . This was a library book and still has the check-out pocket in the front, call number on the spine and a barcode sticker on the front from the library. I haven't tried to remove any of these. This does have a little separation at the top spine/cover. You can see this in the photo. Still stable and perfectly readable.
