Before and after conservation. 2006.177.3
The Hasten wanted poster was treated to remove old adhesive residue and had a deacidification “bath” to remove acids in the paper that contributed to aging and yellowing. Once it dried, it was carefully lined with very thin archival tissue to support the delicate paper. Now that it has been conserved, this document is well equipped to be displayed on exhibit—and will allow the Museum to maintain it in stable condition, indefinitely.
