1915

The Alfa Romeo logo contained two symbols of Milan: the snake of the Visconti family on a light blue background, and a red cross on a white background, surrounded by a small metallic circle with the words ALFA-MILANO.
On models built from 1910 to 1915, the external diameter of the shield was 65 mm, and the words ALFA and MILANO were separated by two figure-of-eight knots.

When Nicola Romeo bought the company the logo was a small steel circle bearing the words: ALFA ROMEO MILANO

1925

1946

After the Alfa P2 won the first world Motor Racing Championship the badge was surrounded by a laurel wreath in respousse metalwork.
Circle diameter rose from 65 to 75 mm.
In 1930 the diameter of the circle was reduced to 60 mm and remained unchanged until 1945.

When the Italian monarchy was abolished and the country became a republic, the Savoy dynasty bows were exchanged for two wavy lines and the badge diameter was reduced to 54 mm.
In 1950 a new badge in enamelled brass but with the same diameter was introduced. In 1960 the same badge design began to be made of plastic.
