The first Carrefour store dates January, 1960. The sign is the name of the building where lived the diverse owners of the mark.
They are implanted in 75 countries today and make a turnover of 76 billions.
Concerning figurines purely Carrefour, it will not be Tintin before 2011s with Tintin.
The Logo Carrefour: the red clocks towards the past and blue, bigger, clocks towards the future. At first too sharp, it was considered as too aggressive, we compared it moreover with an American fist (See picture of the store above).
But what we know less it is that this logo is a trompe-l'oeil. If you look better, you will see that it is the letter "C" is surrounded with some red and blue. See the logo below where I colored the "C" in yellow.
