The State Library of Queensland has an ever expanding collection of maps and posters dating from the mid nineteenth century to the present time. Recently the State Library acquired two posters from an auctioneer in Brisbane, which came to the Conservation Laboratory for de-framing and re-housing. During de-framing, an interesting restoration was discovered on one of the posters. This initiated a search to find out if there was a trend in this type of restoration during this period, which resulted in the discovery of another original poster in the collection produced several decades later that was treated in a similar manner. This paper looks at the research and analysis carried out on the restoration component of the two posters to determine whether they needed to be retained or removed, and the arguments used to justify this choice. It also outlines the conservation treatment options used to stabilise the posters for their long term preservation.
