Although it's not clear from the title, the article is about the origins of fake license plates that were a copy of a NH license plate from the 1980's with the number "UNIX".
Compaq later created similar promotional license plates with the number "LINUX," and yes, they still said "Live Free or Die" on them. I managed to wheedle one out of a trade show representative, knowing the history of the original "UNIX" promotional plates.
Besides the motto and the big number, the plates carry the Compaq logo, "1999" (the year they were made), and the statement "LINUX is a Registered Trademark of Linus Torvalds."
