London: Edmund Ward, (1964). First edition by this publisher. Originally published by Franklin Watts in the U.S. in 1954 and by Bailey & Swinfen in London in 1956. It appears that Edmund Ward took this series over from Bailey & Swinfen in the early 60s and reissued their back catalog. Spine ends lightly bumped otherwise fine in about very good, price-clipped dust jacket with rubbed creasing a few light stains.
