The Alfa Romeo logo from 1947 is a round badge with a red background and a silver border. Inside the badge, there are two symbols: a silver cross which symbolize the city of Milan and a serpent with a human figure in its mouth, representing the Visconti family, the former rulers of Milan. The name of the company, Alfa Romeo, is written in gold letters on the top and bottom of the badge.
I hope you will enjoy it, and happy printing! :)
