"Robert Blake" is the safari hat / khaki outfit of the artist Francois du Toit, whose main body of work can be found here: https://www.artslant.com/global/artists/show/117584-francois-du-toit?tab=ARTWORKS
The artist has been fortunate to grow up in the Sundays River Valley right next to the Addo Elephant National Park. He was again lucky, for the last decade, to be living a stone’s throw from the Sibuya Game Reserve, on the banks of the Bushmans River.
