I bought a bunch of books about the hobbies of wealthy people, and among them was "The Stinger (The Abarth Register Newsletter)," a newsletter for owners of ABARTH, a company that mainly tunes FIAT cars.
This newsletter was apparently produced by Gerald Rothman, a central figure in the movement, who cut, pasted, copied, stapled, and mailed it for about 30 years, but what's interesting is that it sometimes contains handwritten messages.
They were mixed in with other books and materials, and many of the pages were torn apart, so it took a lot of effort to put them together, but when I counted them there were 31 copies in total (some pages were missing).
I doubt there's anyone looking for these, but they're not something that's commonly available, so I think it's quite rare to have this many in stock, so if you're interested, be sure to check them out.
