Around 1930 the farm Chocolate Zaini has produced different series of cards about italian football. I'm not sure about year and I think same card was sold for several years, you could find it buying a chocolate in the shops. These cards are really rare, never seen one complete series. There is also one collection with players of Italy national team at World Cup 1934. Please check 1st card, that team is INTER Milano that during fascism Mussolini has changed name in Ambrosiana (San Ambrogio is the Patron of Milano), the player behind in the center is Giuseppe Meazza, probably the best player ever of any time in Italy. He gives also name to stadium of San Siro, in Milano
