Hans Frank, a 39-year-old lawyer, Nazi Party member, Governor-General of the western part of Poland. 
In 1940, to a reporter for the Völkische Beobachter newspaper:

"In Prague, for example, large red posters were hung up announcing that seven Czechs had been executed that day. 
If I had to hang up a poster every time we shot seven Poles, we'd have to cut down all the Polish forests, 
and we still wouldn't be able to produce enough paper for all the posters I'd need."
