With Original Antique Watercolouring. These accurate and vivid representations of birds are from Henrik Grønvold, Danish naturalist and artist, known for his illustrations of birds. Henrik Grønvold (6 September 1858 – 23 March 1940) was born in in Præstø. He had an early interest in natural history, and an early aptitude for natural history art. His illustrations largely appeared in scientific periodicals, Grønvold also completed numerous plates for Walter Rothschild. The present print can be characterized as being beautifully executed traditional lithography, with an extraordinary rendering in very fine detail, all with original handcolouring, showing the subjects in association with indigenous flowering plants in their natural state and habitat. The colours are bright and very intense on a white medium weight paper and are heightened with arabic gum, to provide them a more glossed and vivid appearance. The condition of these prints is very good. On antique paper, that is still in good conditions.
