It's rather iconic wouldn't you say! Evocative of spooky secret passageways and a hidden staircase plus a host of hauntings at The Mansion/Twin Elms in which Nancy Drew encountered while solving The Hidden Staircase. A new treasure in my collection. As you can see from the original cover painting above in comparison with the book below, there's quite a bit more to the scene from the wider view of the stairs to the expansive wall/ceiling height are shown and the cobwebs are much clearer. The painting itself is more spooky in person. Rudy Nappi was the illustrator for this particular cover and so many other great Nancy Drew covers as well as Hardy Boys covers too.
