My favorite is the General Motors Parade of Progress bus. What about you?

Culver City 1948
In a time when the word “car” was not even heard yet, and people relied on horses to pull their wagons, one woman challenged the status quo.
To prove to the world that her husband’s invention was the future of mobility, Bertha Benz went on the first long-distance journey with an automobile, facing all kinds of challenges but stopping at nothing.
The rest, as they say, is history.
As you can see from the header on my blog, I am a fan of the 50’s and still have a car like the one I drove in college.
Here are some car ads from back then. I can still identify each marque and year.
