I should say the carbon paper is vintage, and in pristine condition, the box a silvery blue. It doesn’t give a very good impression on the Corona Silent but I’m sure will be darker on some of the harder platens. I was hoping, a little bit, to find some used sheets, just out of nosey curiosity. Historical research! But the secrets of the previous owner are still safe as they don’t seem to have used any of the carbon paper at all.
