The Roschchild Mansions

The roschilds built some of the most opulent palaces of all time, which they proceeded to decorate with some of the greatest art collections of all time. The brothers slept in the same bed in a dingy attic bedroom in a ghetto when they were young. When one of the brothers was getting mad at karl for something he had done,  he put things in perspective by saying, was anything more promised to us when we slept together in one attic room in frankfort judengassa?
