Due to an up coming movie and a movie star/director's father shooting off his mouth and spouting some very scary lies, it might be a good idea to check out this site I found. The art and politics of Athur Szyk http://www.ushmm.org/museum/exhibit/online/szyk/Syk was an artist who escaped Nazi Germany and used his art to make the world aware of Hitler's atrocities.
Now might be the time for some remedial viewing.
