A Most Remarkable Poster


This "broadsheet" poster advertising a specific Ingersoll lecture, probably near Boston, in 1878, may be the rarest single piece of Ingersollia in the Museum collection. Posters of this sort were printed on very low-quality, high-acid paper; specimens seldom survive to the present day.

This broadsheet was in fair condition when the Museum acquired it and underwent extensive archival preservation work in order to restore it to its current condition. It was carefully treated to remove acid and cracks and small tears along the edges were rebuilt by hand. The poster was then backed with acid free mounting board and framed behind UV-resisting glass.

After such treatment, the poster can be expected to maintain its current appearance for many years to come.
