The inscription on the photograph appears to be from
the 1860s. The date is not easy to read, but the style of
the inscription is very similar to one on a painting by John Horsburgh b.1835 held by the Scottish
National Portrait Gallery.
John Horsburgh b.1835 is reported to have
flourished 1878-1899. Might this be one of his earlier works?
