What's the name of that font you found Etienne ?
maybe the guys at the selectric museum made a small mistake.... ?
The one I printed with:
The letters are close, but the numbers are really off. They also have this goofy spacing (weird !), The ball's name is Delegate by the way.
Century regular, but as you can see is the "5" different in the top part..
youre right, i have not looked sharp to the numbers, the capital letters are fine as far as i can judge
ps , my ball is "delicate"
