Here is some history that "really, really, really matters."
This is the oldest working McDonald's. It was the third McDonald's that opened in 1953. Some years later Ray Croc came here and like the idea of creating fast food like this. He bought out the name from the McDonald brothers and started the franchise we know today as McDonald's. It turns out this one ended up existing independently than the mainstream one.By doing so, they ended up keeping the original mascot called Speedee. There were no clowns here. At night you can see him with neon lights showing his quick feet.
In 1990, the mainstream McDonald franchise purchased this one and it became part of the whole franchise. Click the following picture so you can read the whole history.
