10c Blue-Black, Frameline (10 var).
Position 75, three complete framelines, partially complete at left, very distinctive Black
color, tied by "Richmond Va. May 13, 1863" circular datestamp on cover to Greenville C.H. S.C., some cover aging and mended tears, stamp with some faint toning around edges, Very Fine appearance, an extremely unusual stamp, Stanely B. Ashbrook wrote in 1938 (copy of letter included) that he believed the color was a changeling from the normal Blue, yet despite his examination of many hundreds of Frameline stamps, this was the first he had ever encountered which had changed so dramatically to Black, we tend to agree with his analysis as a glass will show faint traces of Blue in the corners of the top frame line, ex Haas, with 1996 C.S.A. certificate as "Blue-Black"
