A poster that has survived decades deserves to survive many more. Most damage to vintage posters happens after purchase, through avoidable mistakes in storage or framing, not before it. A little care goes a long way.
Light is the biggest everyday threat
Direct sunlight and strong artificial light both fade printed ink over time, and the damage is cumulative and irreversible. Never hang an original poster in direct sun, and if it’s on permanent display, use conservation or museum-grade UV-filtering glass or acrylic glazing, which blocks the vast majority of the UV light responsible for fading.
Humidity and temperature
Paper is hygroscopic, meaning it absorbs and releases moisture from the air, which causes it to expand, contract, and, over time, weaken. Aim for a stable environment, avoiding damp basements, uninsulated lofts, or rooms prone to big temperature or humidity swings. Consistency matters more than hitting an exact number.
Framing the right way
Always use acid-free mounting board and acid-free mat board, and make sure the poster itself never comes into direct, permanent contact with an adhesive. A linen-backed poster can be safely mounted within a frame using reversible poster hangers or a simple sink mount; never dry mount an original poster to achieve flatness, as this can permanently destroy its value. See our guide comparing dry mounting and linen backing for more detail.
Storing unframed posters flat
For posters not currently on display, flat storage in an acid-free archival folder or portfolio, kept somewhere dry and stable, is generally the gentlest option for a poster’s long-term condition, since it avoids introducing any new fold or roll stress.
Storing unframed posters rolled
If flat storage isn’t practical, rolling is the accepted alternative, provided it’s done correctly. Roll the poster around a wide-diameter acid-free tube, image facing outward, with a sheet of acid-free tissue interleaved to protect the surface, then wrap the whole roll in further acid-free tissue or a breathable archival sleeve. Avoid tight rolling on a narrow tube, which introduces new creasing over time.
Handling
Always handle a poster by its edges, with clean, dry hands, ideally cotton gloves for particularly fragile or valuable pieces. Never lift a poster by a single corner or edge; support it flat with both hands whenever it’s moved.
Insurance
For any collection of meaningful value, check whether it’s covered under a standard home contents policy or whether it needs a specialist fine art or collectibles rider. Many general policies either exclude collectibles or cap them well below their real value.
