>>>In the permenant exhibit at the National Postal Museum in DC, there is a
plexiglass column filled floor to ceiling with thousands (millions?) of the
little round pieces of paper left over when they perforate the stamp edges
--- A very clever use of the left-overs I think!

Glad to see someone's enjoyed our use of chad (the name given to those
bits of left over perforations). I will say, for the record, that gathering up
those billions of tiny pieces of paper was not fun duty for our designer, who,
after helping to bag some of them, was finding bits and pieces of chad on
her clothes and in her purse for months.
