My favorites are: the one of him huddling in his prison garb (around page 35), the closeup of his face (page 47), and the one of him holding his children(?) on page 87, that immediately precedes the poem. I can never complain about my own life, after seeing what this man went through in his.
I'm very glad you're pleased with the book (and glad that you found a copy). It's one of my favorite books among my entire personal library, and one that I never tire of sharing with friends.
