I did a little research and translating... the ones with scans that I checked on COMC, which go with the Autosprint II Serie in the database, are stickers, in Italian only. Yours appear to be cards, featuring, at least with this 66 car, same photographs. Yours has Italian, French, and English.
Additionally, a google search took me to a familiar blog, Cardboard History, and I can see that our friend Billy Kingsley has a very similar motorcycle card from a Series of 100. His has four languages to your three (adds German). He calls his 1976, and I don't doubt him.
Candygum was/is a brand of gum. These may have come in packs of bubble gum cigarettes. But I think there are definitely at least 3 different sets with very similar looks.
I'm going to reevaluate how I collect after the new year. It's just getting way too expensive for the new stuff. Sometimes I just want to buy a pack, not a whole box or even blaster.
