Nathalie,
To each their own... me, I want to be able to *see* my posters... that's why I
have them hanging on the wall in the first place. As far as heat and humidity
goes, I think common sense prevails there. If the environment is comfortable
for humans, it's going to be fine for posters, particularly if they are in
frames with Plexiglas. Obviously, too much heat and/or humidity is going to
encourage bacterial and fungal growth... even tiny paper-eating bugs and
general deterioration -- but if your house is that humid it would hardly be
what most people would call "comfortable for humans". Within reason, cool, dry
air is best. But there is a such a thing as air that is too dry which will
cause paper to get brittle -- but again, that doesn't happen in a comfortable
for humans environment. People don't think about bacteria and bugs attacking
posters, but in the case of items which have been linen backed, we only just
discovered in recent years that over the decades a lot of backers did!
not put anti-fungal or insecticide additives in the wheat paste glue they
used to back the poster onto the linen with. In the right circumstances, this
can lead to a bacterial or insect infestation literally eating away at older
linen backed posters. I think most modern backers now use additives, but I
wouldn't be surprised if there aren't some out there who still don't -- this is
probably something everyone should ask about when choosing a backer.
