Okay, I've got an Italian assignment due tomorrow and l have not covered one of the topics - the history of Fiat logo. PLEASE help, most of the sites are blocked on my computer under blogs!

1899
The ''Fabbrica Italiana Automobili Torino'' company is founded in Turin, & a special poster is created to celebrate the event.At the top left of the poster, the artist includes a small parchment containing the company name.This very elaborate design eventually becomes the first FIAT logo.
1901
FIAT decides to apply a proper logo on its cars: a small enamelled brass plate in the centre of which the name
FIAT appears, with the characteristic A, which has remained practically unchanged up to the present day.
1904
The logo becomes oval in shape, taking on an original liberty style that continues to be produced until the 1920s.
1925
The logo becomes circular, with the FIAT name in red on a white background.
The stylised laurel wreath around the outside is intended to celebrate FIAT’s victorious participation in the first competitive motor races.
1931
The automotive project begins to dominate even in terms of communication, & the logo, from being circular & richly detailed, suddenly becomes a rectangle taken up almost entirely by the FIAT name.
1932
The rectangular shape takes the form of a shield, a symbol rather more fitting for the radiator grilles on
the new models.
With a series of slight variations, this logo is used on FIAT cars up until 1968.
1999
The brand’s 100th anniversary sees a return to the style of the logo from the 1920s.
The version chosen has a blue background, a chrome-plated logo, with the characteristic A, & a more
stylised laurel wreath.
2006
The new FIAT logo is launched, seen for the first time on the Bravo, & set to be used on all future
FIAT vehicles.
