A Study of Oak Leaves in Autumn (Self-portrait)

McTaggart employed loose, expressive brushstrokes and thick paint to capture texture, particularly in the subject's hat and beard. The resulting surface is tactile and almost three-dimensional in places, characteristic of his post-Impressionist style.

Created in 1896, the painting is now held in the Scottish National Gallery, a testament to McTaggart's significance in Scottish art. The artist was active from the mid-19th century until his death in 1910.
