Before treatment / After treatment
The painting was in a degraded condition, with two large tears, dirt across the surface, and a degraded, darkened varnish covering the painting. The painting was cleaned and the discoloured varnish removed. The tears were repaired using a thread-by-thread mending technique. A conservation-grade varnish was applied, and the losses filled and inpainted to match the original surrounding paint layer.
The most obvious damage was the dark yellow stains. The paper was washed using specialist techniques and solutions to reduce the staining. Final treatment steps involved humidifying and pressing the drawing, then rehousing it in a 100% cotton rag mountboard.
The globe was severely discoloured, due to degradation of the natural resin varnish layer. There was some cracking and losses of both the plaster globe and paper map. The loose elements were secured. The discoloured varnish was removed and the surface cleaned. Areas of loss were filled and losses were inpainted, followed by a final spray-coating of varnish.
The painting had suffered extensive, water-related damage, causing lifting of the paint layer from the canvas support. Flaking paint was re-adhered to the canvas. Once the paint was secure, losses in the composition were reintegrated using conservation-grade materials.
The Honour Roll had been splashed with off white oil paint. Removal of the white paint was undertaken using a solvent gel. This enabled removal of the white paint without affecting the underlying gold lettering. Removal of the old varnish layer was undertaken with organic solvents. Revarnishing and selective retouching in areas of loss were undertaken.
