That's a picture of a floppy disk in a museum, though -- and it too probably contains the disassembled source code :)

If I had to guess, the only people who had access to the original source are rtm, whoever he gave it to, and whoever accessed his account at Cornell when they looked through his homedir.

And it's unlikely that any of them would have distributed it. Remember, at the time this code was potentially really dangerous; this was essentially a new type of attack that folks weren't really ready or prepared to defend against.
