Superb

A product of a large format negative (10x12", possibly 11x14") on a glass plate, and a "rectilinear" lens. Those lenses were made obsolete because the largest that they would open was usually F8, so they were only practical for non moving objects. But they gave a beautiful, sharp image.

Ever see old pictures of a racing car at speed--where the car seemed to be lunging forward, and the wheels were oval? A product of a "focal  plane" shutter, another early photo item, that was discarded--although a Leica that I had was relatively modern, and it had a focal plane.
