Grand prix 1984 packet with back variant and Senna rookie card

mpg

I have this packet full/sealed, I know that is possible to find ayrton senna rookie in this collection.
My packet,, besides being rare, is some sort of variant packaging because every other copy has the plain "grand prix" logo on the back but mine has an advert for "mister day parmalat". So I think it is very interesting to packets collectors , especially with the history of Parmalat as a sponsor in F1.
