This set included the U.K. printings of John Gardner's first four James Bond novels. "Licence Renewed" had three different covers, the blue one featuring die cut bullet holes borrowing from the Raymond Hawkey designed "Thunderball" cover from the 1960's. The two "Icebreaker" covers have differences explained on the Slight Cover Variations page. The edition of "Role Of Honour", which probably isn't really part of this series but features the same fonts, was only available in the U.K., with other countries only encountering this title in paperback for the first time in the Sniper series. Sadly, no cover artists were credited for these designs.
