While looking through a selection of James Leasor covers I came across the French Edition Pocket of ‘Passport To Oblivion’ and felt the cover image looked vaguely familiar. I’ve thought this in the past but on further investigate would usually find they were just similar but this time these two covers are not just similar but identical. Both books were published in 1967 so which came first?

Left Edition Pocket N°569 <> Right PAN Books Ltd X649

UPDATE Since adding this post I now have the French title in my hand and in the back it says it was published on 30th December 1967 and on the back cover says “Notre Couverture: © Pan Books Ltd. Loudres” so that probably answers the question but did they use anymore?
