Where can i find a pic of Hitler as a Demon or Evil thing?

Okay, so right now in school I'm learning about Adolf Hitler and we were watching a film and it had a painting of him as this sorta demon or evil thing and at the bottom it said My first pastel painting, 1889. It was weird because it looked like hitler when he was older, but he was just born that year. Long story short, I can't find the pic anywhere online. Can someone give me a website or something?
