Affiches Charles Verneau
Original stone lithograph French 6 Panel printed in 1896. (92in. x 117in.), it is authentic, used advertisement by the artist Théophile Alexandre Steinlen for a printer named Charles Verneau.

Poster was received mounted to tissue paper with double sided tape used to hold the overlaps together. The top and bottom sections on the left hand side were delaminating. The poster had previous restoration and had most likely been conserved prior to being mounted on the tissue. Areas of the poster were thin, most likely from previous demounting. The corners had also been eaten away by silverfish.

Procedures

In order to demount and then remount the poster it was separated into the 6 individual sections of paper it was originally printed on. To accomplish this, the tape was manually removed from each piece with the use of a heat gun to facilitate the process. However, because of the tape, some of the overlap was lost.

The first piece of the poster was humidified as a test of how durable the previous restoration was. Once this was established the poster was gently rinsed and put through an isinglass gelatin process in order to temporarily apply a hollytex paper facing to the front of the poster in order to remove the tissue from the back. The tissue was then removed by hand. This process was then repeated for each of the remaining sections.

The poster was then mounted with the facing still on to a linen and masa substrate using archival glue. The facing was removed after the poster had cured. The poster was almost completely intact and a minimal amount of additional restoration was performed. The restoration was contained to the areas in the black of the two skirts on the left and the top of the basket and the brown skirt on the right. In these sections the pigment had cracked or lost some of the paper.

Conclusion

Due to the isinglass process and using a facing, we were able to preserve the majority of the previous restoration work and the original paper. To view a complete documentation of the steps used to conserve this poster please visit www.postermountain.blogspot.com
