Nancy Drew Mystery Stories The Secret Of The Old Clock Carolyn Keene #1 1959, appears to be the first edition but you be the judge; see photos. Upon information and belief, this copy was purchased around 1967 and is 56 years old! This is a rare and wonderful example of a pristine, well-kept vintage copy with only one owner. Lovingly stored without circulating or reading, by a Nancy Drew Collector until death in a smoke-free, pet-free, temperature and humidity-controlled environment, out of sunlight.
