Thank you for submitting your item for appraisal. These appear to be two John Tarrant Kenny reproduction L. Hitchcok stencil decorated side chairs, produced in the second half of the 20th century. The Hitchcock chair was the first american mass produced chair and the reproductions were also produced in large numbers. The estimate for the two chairs is based on recent auction results. There is no measurement for the sentimental value you might attach to the item.
