I bought the deluxe set from a salesman outside the PX at Schofield Barracks, HI, in 1988. He was pretty happy, but a few weeks later the mail room folks were not amused. I also got the complete and un-expurgated 100 volume set “Great Books Of All Time, Which You Will Probably Never Read”.
The World Book had a nice set, it is amazing to see how prevalent propaganda and so-called political correctness has rotted thoroughly into modern tomes. The set I have dates from 1966.
I also find indispensible, a 30s era Merriam-Websters dictionary.

LOL, I remember letting the salesmen into my home outside of FT. Lewis, Wa. in 72-73.
I never could figure out how they went from giving me a set of encyclopedias for free to several hundred dollars of payments, then a few years later I was giving the same pitch.
