Just take a look at this kid.
This is Leon Trotsky the world-famous revolutionary and he's eighteen. Only he's not yet Leon Trotsky. Here, in this picture, he's still Lev Davidovich Bronstein, a Jewish kid in Czarist Russia.
What's going on in his head? What's it like to be a Jewish kid in Czarist Russia?
How much of the Leon Trotsky to be is already in Lev Bronstein - and how much of Lev Bronstein will one day be in Leon Trotsky?
