|Ransome had illustrated the succeeding titles from Peter Duck onwards, and these had been greatly appreciated by readers. Finally in November 1938 Cape replaced the remaining Webb illustrations with Ransome's in a 3rd edition; the drawings were at first credited to one of his principal characters Nancy Blackett. A 4th edition, largely unchanged but with new typesetting, was published in August 1958.
The jacket listed here is from the 1964 4th printing; it was later felt that there were too many dark drawings, and one was replaced by a lighter alternative. Otherwise, this design has with very minor alterations survived for decades.
Incidentally, it seems that the designer of these jackets is unknown. I tentatively suggest that he may have been Clive Gardiner (1891-1960) whose work "White City, Harringay Park" (1927) for the London Underground included elements very similar to the coloured segments which separated first Webb's and then Ransome's drawings.
