 The first four volumes of the Danas were reintroduced with new jacket art and frontispieces, but no spine symbols or numbering.The books were green with Jean and Louise illustrated on a haunted path at night on green endpages.The series drew interest again so subsequent volumes were updated and released, with spine symbols, until the publication of a new volume (already written and set for printing in 1945) in 1952; new volumes were released once a year.
