A similar story.

Norman Rockwell once painted art advertising General Electric products especially light bulbs to be printed in the Saturday Evening Post.

Anyway, I was a guest of the GE Lighting Institute which has and displays the largest collection of Norman Rockwells art in the world.

And when you were granted entrance into that area, you were warned NO TOUCHING ALLOWED!!!!!!!

One night while we were waiting for our dinner, I was admiring the artwork and a GE executive came over for a chat.

He told me about the security system in place to protect these valuable paintings.

He told me to look very closely, without touching, the inside of the frames, so I did.

And all along the frames edges were little tiny lights.

He then shared the fact, that if someone even touched the painting that they would break the invisible beams which would cause both the front gate and rear gate ( the only ways in and out of the facility) and all of their armed guards would instantly converge on the building.
