|Boy and Granddad by Phyllis Simard|
Rockwell was looked down upon by some in the "Fine Arts" community as a "mere illustrator" until after his death when the pendulum swung and his body of work was recognized as art. Too late for Rockwell, but Wikipedia remarks that he didn't mind being called an illustrator. It's what he called himself.
I would encourage all my students: follow your personal dreams. There will always be people who make less of them; you are the one who can make them come true.
