With three exceptions books in the US series were also published in the Canadian series. Of the 25 US issues, 24 had a date the same as or after the Canadian issue. Death Be My Destiny is the only exception with a January 1950 Canadian date and a November 1949 US date.
Paired with Death Be My Destiny is the only early paperback from Dell with a dust jacket. Note that the DJ is used to opposite effect. The Export DJ covers a more "sexed-up" cover while the Dell does the opposite. There is also a remarkable design similarity between the books.
