When you're a carpenter making a beautiful chest of drawers, you're not going to use a piece of plywood on the back, even though it faces the wall and nobody will ever see it. You'll know it's there, so you're going to use a beautiful piece of wood on the back.
I've known those pieces ever since I was about 16 or 17; I also at that time was taken to meet Charles Ives whom I got to know fairly well. He was the one who wrote a recommendation for me to get into college.
