I remember my mom had a big collection of copies of Saturday Evening Post magazines and that was really my introduction to those great illustrators.
That's something I learned in art school. I studied graphic design in Germany and my professor emphasized the responsibility that designers and illustrators have towards the people they create things for.
I was a little shocked at how adult some of the humor was because I was never that into animation before and when I watched 'Shrek' I really laughed out loud.
