Leather covered wire chair designed by Ray and Charles Eames and made in by Herman Miller in the 1960s. Beautifully worn leather (sometimes called the postman's bag) with original backing and label. Model number is  DKX but base is, however, an H base, not an X base but it came with the chair and works well ( Herman Miller replaced the X base in later models as it was sturdier). Older boot glides are original too.
