Yup, they are still in business. They are about the only ones making
Vectographs for testing eyes - primary customers being opticians. Does
anyone ever remember seeing the Vectograph of the Fly? It was very
interesting to look at, lots of detail. I am not sure if they made it or
not. I would like to find some more of them.

I am not sure what CSO wants to protect, unless it is how they produce
these images. My guess might be that they are not using Matrix Film, but
perhaps printed Matrices, or perhaps some sort of printer.
