Fine Art/John Falter
My wifes great grandfather was John Falter. She has a charcoal sketch of her mother that he did in 1934. Can you estimate a value on that on advise us the best way to protect it. We are not sure if it was sprayed with a protective coating to stabize the charcoal.
Dear Glenn, Generally paintings by John Falter do not have great value on the art market, usually under $1,500. However when they are more Regionalist in style and subject they bring much stronger prices, well into five figures. Regarding your artwork there is a difference between sentimental value and market value. A charcoal sketch of the artist's granddaughter would have little appeal to collectors.
The best way to protect your drawing is to consult a paper conservator. He will advise you if it needs to be deacidified and/or thymolized. And in any event it should be mounted in a 100% (acid free)rag mat.
