Nancy Drew Hardcover book vintage Mystery of the Brass Bound Truck

The mystery of the brass bound trunk is the 17th volume in the Nancy Drew mystery stories series published under the pseudonym Carolyn Greene. It was first published in 1940 by Grosset & Dunlap and was extremely revised for publication in 1976. The pages in this book appear to be clean there is writing (some names and address) inside the front cover see pics and on the very back page a couple circles in pencil (see pic) other than that normal vintage wear mainly yellowing of pages. However I have taken multiple pics so please refer to them. Comes from a smoke free home. Thank you.
