The Secret of the Old Clock (Nancy Drew #1)

No book-club issue applies. The reprint traps are format changes: the Nancy silhouette added to the cover and jacket, orange silhouette endpapers, the 1937 reduction to a frontispiece only with expanded jacket copy, the 1943 updated frontispiece, the 1950 wraparound jacket with Bill Gillies artwork continuing across the spine, and the 1959 textual revision with five new illustrations. Later "picture cover" (pictorial-board, jacketless) editions and the revised 1959 text are entirely different books from the 1930A-1 format.
