Someone else's art

Occasionally many of us feel impelled to photograph someone else's art. I was in a portakabin sheltering from the rain while my car was being washed, bizarre I agree, but it was sunny when I planned it.

On the interior wall was this picture depicting famous people over the ages. I could not photograph it all and at the same time preserve recognisability so cropped  the image to highlight one man who changed the planet.
