Question about storing posters

Not so much an issue of antiques, but I've recently been asked to
inventory the possessions of a small school with a view of placing
some items on display, and storing other items safely. I came across
posters for school festivities that have been painted on cardboard in
the 1940s. They're currently rolled up and stored in a dry but cold
attic. Does anyone have expertise on the subject of what would be the
best way to store them so they'll keep in good shape for the future?

I always recommend the Australian Recollections site for an intro to
curatorial stuff.
However their website seems flakey these days, so you might have to get
there through web-search's cache.

The Palimpsest mailing list is also interesting for paper conservation.

Rolled up or flattened out?

Ask your local expert frame shop or gallery. I believe rolled up (not
creased) is just as adequate as flat storage, and easier to maintain.
You can store rolled-up posters in very firm cardboard tubes like
architects use, or those mailers that FedEx uses, if they are an
appropriate size. This keeps the posters rolled, not creased, and
prevents them from getting squashed. In any event, any paper used as
inter-leaves or other paper products that touch the posters should
absolutely be acid-free. Acid-free papers are available from art
supply stores, frame shops and in some cases, fabric shops.

Thanks for the tips, I'll look into this!
