Thanks for the information.
The roll bar came with, though not installed in, my 64 Giulia Spider.
With the sticker dated 1992, I certain that many things have changed in the last 25 years.
We have a lot of members who do, or did, race Alfa Spiders or other such sport cars; maybe one of them participated in this race.
