Connection between Mainhattan and Manhattan

I think there are a lot of similarities between Mainhattan and Manhattan. Manhattan is America´s Financial District and Mainhattan is of course Germany´s Financial District perhaps Europe´s, because of the European Central Bank.
Manhattan has a skyline and Mainhattan is the only city in Europe, which has also a skyline. Frankfurt has a stock market, too but Mainhattan is not as big as Manhattan.
Mainhattan has also a sculpture nearby the stock exchange, but it´s a bear and a bull together. The Frankfurt Stock Exchange (DBAG=Deutsche Börsen Aktien Gesellschaft) is not as old as the NYSE is, it was founded in 1992.
