I would like to point out that these would really be reissues, as opposed to reprints, especially since reprints have a very negative connotation, and are usually done without permission of the original producer of the set, and I have never seen a "reprint" of any of Bob's sets.
I loved picking up Bob's Inside Pitch newsletters several years ago. You get to hear a lot of information in Bob's own "voice" and you get to feel like you know him a little bit. Highly recommend picking them up if you see them. And not just because they contain the scarcest (two card) set that Bob produced!
Again, although I don't really like him calling subsequent printings of his sets reprints, Bob did talk about them using that term. This is the information that I have always used on Bob's black and white set, from Bob in 1976:
