If the bow is not excessive, I wouldn't try and fix it. By straightening the
cardboard you will be stretching the photographic print, and you don't know what
will happen then. Perhpas you will end up with a crease or tear. These types
of photo cards are bone dry. I know collectors who have accidentally snapped
in half cards and cabinet cards when trying to correct them.
