here's a scenario. You have several posters that you want to
display. You can't afford to frame them all right now but just
need a cheaper method for now.
want the cheapest way to both give some protection and be able
to display your prize too.
let's start with the simplest. This is what I call TEMPORARY
gone into small collector shops and seen posters, what we call
in the industry, 'boarded and bagged'. This is also done a lot
for collector shows. They would take an acid free board and
attach the poster to it with small rolled pieces of acid free
tape from the back (almost like tacking it) in several major
points. Then they would put it in a large acid free bag and
tape the bag down tight from the back side. The tighter the
bag was taped the better and smoother the poster looked. The
posters could then be stood up so customers could flip through
them to see what was available.
