The day after I got my first postcard from the USA, I received these two postcards from my friend, Ashor, as well! I am terribly in love with New York City’s skyline! I think it is one of the most magnificent city views in the world. More on Rockefeller though… It was very interesting for me to find out that the world’s first billionaire, John D. Rockefeller, is considered the richest man that ever lived. His 19th century $1 billion seems to pale against the $72.4 billion fortune of the Mexican telecoms magnate and world’s richest man, Carlos Slim Helú… One would be wrong, you see because the value of money changes all the time. John D. Rockefeller’s fortune then, would be $318.3 billion today. That is a lot of money!
