A scan of the back side of the dust jacket is not available, so the lack of a copyright notice is not certain. However, at least one dust jacket featuring the same cover art, but from a different printing, is known to be published without a copyright notice.

• File:The Secret of Red Gate Farm (1931) front and back covers and spine, 1944 printing.jpg
• File:The Secret of Red Gate Farm (1931) front and back flaps, 1944 printing.jpg

Furthermore, front and back scans for two other Nancy Drew dust jackets are available on Wikimedia Commons, and none of them have a copyright notice.

• The Secret of the Old Clock: front, back
• The Secret at Shadow Ranch: front, back

Thus it is reasonable to assume that the back side of the dust jacket does not have a copyright notice.
