Touch Tone! An Antique!
I'm with Dave, I'm feeling really old.
Bell used to have the Installers handwrite the labels. There was also a Stamping machine that you adjusted one number at a time (kind of like the things they used to use in Supermarkets to label the cans - only fancier).
The font was a Sans Serif - kind of like Helvetica Bold, as I recall.
Usually it was also a bit smudgy, and misaligned. I don't know if there's a font for that though....
