Eric Enstrom is famous for his 1918 photograph of Charles Walden in Bovey, Minnesota. The photo is known as Grace and depicts Walden saying a prayer over a simple meal. In 2002, "Grace" was designated the state photograph of Minnesota.
I don't think this would be considered, "Catholic Art", but certainly it is Christian. I grew up with this hanging in the dining room at our house, I always thought the man looked like Santa. I'm glad to finally know a little about it's origin.
