Too much walking yesterday?

At least I didn’t go out at all today. Standing on my balance pads working on the computer all day. Suddenly I came to think about my Blip! I have to take a photo. As I saw the light from my computer, mirrored in the glass of the lithography of Hans Ekwall, I thought: That’s a good picture of my day!
This is a true lithography (Lithos=Stone) The printing is from a stone.
