Historic posters have often survived in far from ideal conditions and may have visible signs of age, such as tears, folds, edge nicks, creases and surface dirt. Sometimes the poster itself has become fragile due to chemical changes in the paper or because of stress along fold lines. This can make posters difficult to store, handle and display. In such cases, sympathetic conservation can dramatically improve condition and significantly enhance appearance.
Twentieth Century Posters only recommends museum approved conservation methods, which are fully reversible and free of harmful chemicals. We believe that the best results are achieved by mounting posters on Japan tissue backing, which stabilises the artefact while maintaining the original ‘feel’ of the poster – unlike linen backed conservation methods which add weight and, in our opinion, change the nature of the poster. For long term storage we recommend that posters and ephemera are kept flat in protective Melinex (or ‘Mylar’) polyester sleeves, which are available from conservation suppliers.
