Answer personally I would address the bank president by name, which shouldn't be too hard to find out. If nothing else then use a generic title like to the president of xyz bank or to whom it may concern. If the bank is somewhat large and has one you may want to contact the public relations person instead as they will most likely end up being the ones to handle it anyways.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
