IIRC, it's from the days they used carbon based inks which imparted a

I think the carbon acts as an anti-static. In a picture framing lesson
at our local 'Framers' I was told it is the only way to get the glass
dust-free. It certainly works for that. You get a handful of screwed up
newspaper and polish the glass with it.

I understood modern inks were carbon free? They certainly don't make your
hands back as once.
