What you are seeing is the "Firt Edition Thus", which was a 1996 reprint by Simon & Schuster, as seen on this page: http://www.cusslermen.com/medcaperss.htm
The Mediterranean Caper was first printed in 1973 as a paperback.
You could order the Limited edition of Mayday, printed by James Cahill Publishing (Mayday is the same book, was originally released in the UK under that title)
