In the early 1970's, Italia tire manufacturer Pirelli, long-term supplier of Alfa-Romeo, used Alfas extensively throughout their advertising campaigns.

In some cases, they used the Junior Zagato.

Around 1971, Pirelli ran a campaign using a white JZ 1300 (chassis-number unknown) in an almost psychedelic setting with multi colored neon lights reflecting in the Plexiglas front of the car.

This photo was used for a poster.

The poster in turn was used in magazine advertisements, which included a ticket that could be filled-out with one's name and address and sent to Pirelli who in turn would send you such a poster for free!

After years of hunting, I finally managed to lay my hands on one of the posters!
It's in far-from-mint condition but I'm VERY happy that I finally got one!

Also depicted is the aforementioned magazine ad (in French in this case).
