I have to agree with Larry Norman.  I loaned some really rare Duo-Art
rolls about 10 years ago to a Reproducing roll recutter.  The only time
I've seen them since was when they were listed in an auction of his
original rolls.  Of course, they may not have been the exact same ones
I loaned, but I have to wonder.

I have a number of Duo-Art masters that have never been commercially
cut that I'm thinking of having done, when there's a perforator that
can do an accurate replica quality copy, but I'm nervous of loaning
them.
