The artist David Allan must have heard Niel and his brother Donald on many occasions as captured in this painting of c.1780. Image from National Galleries of Scotland.
Here we see the Raeburn portrait of Niel Gow in the care of Perth and Kinross Council. Presumably this is the version that previously hung in Perth County Hall. Compare this with the Scottish National Portrait Gallery painting in the next post. Image from http://www.artuk.org/artworks/niel-gow-17271807-129700
