Spy vs Spy Omnibus is a rarer Spy vs Spy publication, being a hardcover collection of Spy vs Spy comics. It contains all of the information found in The Complete Casebook, but with each comic in the exact size of its original print, some more extra content, and with a preface about the Omnibus vs The Complete Casebook. Like the Complete Casebook, it contains information about Antonio Prohías, behind the scenes information, and more. It is a rarer publication, and is often very expensive, with the lowest priced copies being usually priced in the hundreds.
