What is the best/simplest way to take the curl out of charts that have been
tightly rolled ??

I just pruchased some used charts on ebay and the seller rolled them up and
shipped them in a 2" mailing tube. I always store my charts folded in half
or quarters in chart draws. In this instance, there are only 3 charts, but
this seller will be shipping me about 50-60 more and I expect I will have
this same problem with them. (I'm trying to talk him into shipping them flat
(media rate) or in larger dia. mailing tubes.
