This artwork features a post-impressionist portrait of a bearded man, known as the postman Joseph Roulin, set against a vibrant, decorative background. The man occupies the center of the frame, facing forward with a steady, gentle expression. He wears a dark blue uniform cap with the word "POSTES" printed in gold lettering across the front, matching his deep blue coat which features prominent gold buttons.
His face and iconic, voluminous beard are rendered in warm, rich tones of yellow, ochre, and brown, with visible, textured brushstrokes characteristic of the post-impressionist style. The background is a stark contrast, consisting of a lively, flat green field decorated with scattered, stylized wildflowers including white daisies and red poppies. The composition is balanced and symmetrical, focusing entirely on the subject’s visage.
The colour palette is dominated by the striking opposition between the cool, deep blue of the uniform and the bright, earthy yellows of the subject's beard and face. These tones are punctuated by the fresh greens and bright white and red floral accents in the background. The style is heavily textured, emphasizing expressive, thick paint application that creates movement throughout the image, lending an emotive and timeless quality to the portrait.
