Steve,
Did you notice if the 1991 Topps cards had brighteners added to the red ink? I have spent a lot of time with the 1991 Topps DS set and most if not all seem to have brightener added to the red ink.
Since the DS set was printed in the early stages on the 1991 Topps print run, this should mean that the 1991 Topps set was printed mainly with the red brightener as well. I had always wondered what % of 1991 Topps production had the brightener added....wondering if you have an answer to that question.
Impressive that you have cataloged all of this. Thanks in advance.
