Incidentally I say "no big deal" only because the iso itself is available from the FreeBSD project, so it isn't exactly rare. But I think the scans are.

Where did you get this distribution?  The one I could easily find, https://archive.org/details/vax-svr2 , has serious filesystem problems that can easily be seen by running an fsck on boot.

 
Speaking of Unix History, following that link led me to a copy of what I think was the first 4.4BSD-Lite based FreeBSD iso -it's from June 1995. No big deal *except* that it includes a scan of the cover, something that looks like an insert and it consists of two cds. I haven't had a chance to look at the cds yet so I don't know what's on them.

IMO the scans are the big deal and why I'm posting the link to it here. Apologies in advance for any lapses in etiquette:
