You are bidding on the hardcover book, The Black Spaniel Mystery by Betty Cavanna.  This book is the original 1945 edition by The Westminster Press.  It does have wear but is  in good condition.  The binding is solid.  The pages are clean and unmarked.  The endpapers, however, have darkened from age, and the dust jacket does have wear on the edges, particularly on the back bottom edge.  Please take these condition issues into account if you decide to bid.  This is still a good, readable, book.
