Histoire de cas d’un tableau changeant en papier
Three-way pictures enable one to see two or three different images depending on the position of the viewer. They are made from paintings on canvas and wood, drawings or prints. The present article describes the conservation of one example of this type of object, assembled using three lithographs on paper. One of the lithographs is attached to the back of a wooden box frame. The other two images have been cut and assembled back to back in narrow strips. The strips are held vertically and perpendicularly to the background image in vertical slots made at the top and bottom of the support. During the treatment, two mock-ups of the work were constructed, one to find a practical method of cleaning the paper by an aqueous method, the other to evaluate the effectiveness under tension of several adhesives, textiles and papers subjected to variations in humidity. It was not until the materials and the method of mounting had been chosen that the object was disassembled and the paper cleaned and repaired. The repaired strips were attached to the stretcher of the support with narrow paper hinges. The support was repaired and the wood sealed before repositioning of the background lithograph. A matte placed in front of the support allowed the mounting system to remain hidden. The work was framed under glass. Decisions made throughout the various stages of treatment are explained.
