Vintage Nancy Drew book The Hidden Staircase and 49 similar items

This is a vintage 1959 hardcover book, The Hidden Staircase by Carolyn Keene, from her Nancy Drew Mystery Stories. It does not have its dust jacket. The cover shows some mild wear, but all of the pages are intact and very clean. There is one spot where the book is kind of separating where the pages meet the spine (there's probably a term for this, but I don't know it), but the book is not coming apart and the pages aren't falling out or anything. There are also a couple of pages toward the middle where there's some wrinkling, like maybe they were handled by damp little hands (perhaps by the pool?), but it's just a couple of pages and it's not severe. So, there are a few cosmetic issues, but overall it's in perfectly good reading condition. Asking $3.00 obo. Everything I have listed for sale is "or best offer", so feel free to make an offer. ~~~~~ ALL ITEMS ARE AVAILABLE FOR LOCAL PICKUP. I sell a huge variety of stuff to supplement my income and help me put the last of my kids through college. Some items come from flea markets or estate sales, and some come from around our home, but many items come to me from my extended family of hardcore hoarders. So, the variety really can be vast and unpredictable. Please check back often, because you really never know what I will have from one day to the next! Thanks for visiting and have a great day!
