I apparently have had this for quite some awhile. I don't recall how or just when I got it. I just noticed though that it is the only copy with a dust jacket. The cover color is different as is the print on the spine.

That's quite the numismatic oddity! Ken Bressett and I have had many interesting conversations about the highways and byways traveled by the Red Book over the years. I remember him telling me about Chinese counterfeits --- essentially pirated publications of the book, printed clandestinely and completely unauthorized by Whitman Publishing. I believe this is an example of just such a counterfeit.

A natural question might be, "Why on Earth would anyone print a fake Red Book?" Consider this: The 1965 (18th) edition, published in 1964, sold 1.2 million copies --- ranking it fifth on the list of best-selling nonfiction (ahead of Dale Carnegie's "How to Win Friends and Influence People" [no. 6] and John F. Kennedy's "Profiles in Courage" [no. 9]). Apparently someone with more understanding of printing presses and not so much of American copyright law got their hands on printing plates or otherwise arranged to pirate this tempting treasure.

This was probably made in 1966 (which was the publication year of the authentic 1967 edition) or perhaps in 1967. How many were made, and how were they distributed? I don't know. . . . but it suggests some intriguing scenarios, doesn't it?
