    That's carbonless copy paper.  It's still used to
make multi-part forms, so it's available as a supply
for printers who make forms. You can get large
rolls of it here:

    Various widths are available, but the usual rolls are long,
33,000 feet or so.  So you would need a supply of cardboard
cores and a winder.
