Lithograph by Henry Moore
This signed lithograph by Henry Moore was brought in to the studio recently. It was bought by the present owner in the seventies. She noticed recently that "it was starting to look a bit dull" and that brown spots were begining to appear. One can see how off white it had become by compairing the paper print colour in the slide show to a piece of new paper I placed next to it. On removing it from the frame the reason became obvious. The whole of the back of the paper (verso) was very brown. This discolouration is evidece of acidity that has come about through being in contact with the hardboard backing of the frame. It is essntial for works of art on paper to be separated from the wooden backing of a frame by a piece of acid free barrier board. Otherwise, as is happening to this Henry Moore lithgraph, the verso of the paper becomes more and more discoloured and acidic until it eventually works its way to the front of the paper(recto) This can be seen on the thin deckled edge quite clearly and also the spots of brown foxing and general discolouration: the reason why the image was looking dull to the client. This standard of work is always printed on good quality hand made paper using stable artists quality inks so it will respond in an ideal way to washing and conservation bleaching. This get rid of the staining and the acidity and ensures that the atrwork will survive and keep its value into the future.
