grb090423, When I first started work I was typing (on an old, manual typewriter) documents to release shipments.
The documents needed 3 further copies and we used a sheet of carbon paper between each A4 sheet. Any mistakes made could only be corrected - using a Tippex brush - on the first, original sheet (for the customer).
The carbon paper was used and reused many times.
This is where CC come from - Carbon Copy.
Just in case you're interested 😁
