The first edition of Child Whispers was published in 1922 and was issued in orange cardwraps. For the new edition/first edition thus published the following year, the format was changed to a brown, octavo sized hardback with a dustwrapper. Only one other title was published in this same format, namely the first edition of Real Fairies, also in the same year.
As collectors of early Enid Blyton titles will know, copies of these hardback books without a dustwrapper do occasionally turn up on the open market, whereas a copy with a dustwrapper is rarely offered for sale. For this reason it is probably not widely known that there are two different versions of the Child Whispers dustwrapper and that the differences are only found on the rear panel.
