Sorry for the bad quality.
My grandfather had this in his office. He worked as a computer engineer so I initally thought it was a zoomed-in picture of a computer chip or something, but maybe it is something large.
He’s not alive anymore so I can’t ask him. If somebody can help me out, that would be great.
It looks to be about the size of a briefcase based on those screw holes. It would make sense for the picture to be taken by someone from above.
