Most of the posters are paper based. These have been mechanically cleaned and flattened with paper repairs carried out using a selection of high quality Japanese papers and a wheat starch paste adhesive. Several posters had damaging adhesive residues and tapes adhered to the verso and these were all removed successfully. They are now stored individually within polyester enclosures to ensure their long term preservation.
A small number of posters are printed textiles. These items have undergone light cleaning and repair where appropriate. The posters have now been given custom made storage using high quality conservation grade materials and are now stored rolled alongside other textile collections.
All treatments are fully reversible and have been documented and attached to the catalogue. This conservation work is part of the School's HLF funded Mackintosh Conservation and Access Project.
