There have been many articles on this subject so I will only touch on it briefly. If you are going to display a vintage poster, linen backing and then framing it is the best way. Not all posters need linen backing however, but if it is an older poster and you wish to preserve it, it is a good idea. If you are not going to linen back it, it should be framed with acid free backing and UV filtered Plexiglas. Do not use glass. Glass can stick to the face of a poster over time. Do not have your poster dry mounted to foam core as many collectors believe this to be undesirable.

If you collect posters and you do not wish to frame all of them, storing them can become a challenge. The preferred method for rolled posters would be flat, but this is not feasible for everyone so the next best thing is to store them rolled, but NOT in cardboard tubes. The acid from cardboard can age/yellow a poster. Plastic tubes are fine. Some say that over time fumes from PVC tubes can stain posters. We keep our rolled posters wrapped in plastic bags and insert them into open tubes and keep them out of the light to help prevent aging/yellowing. Rolled posters should be stored STANDING UP if possible. If a rolled poster is stored lying down, over time it may sag and waves can develop.

For long term storage of folded posters we keep them in Mylar bags with acid free backing, NOT REGULAR CARDBOARD.

Folding and unfolding posters can cause excessive wear on the fold lines and possibly cause separations. Try not to unfold your stored posters.

Light Box Displays look great in home theatres, however they can fade posters over time and ruin their value. Do not put expensive posters in them.
