Texas painter Robert Julian Onderdonk, who was active in the late 19th and early 20th centuries, is considered an “American Impressionist”, and in known in particular for his landscapes featuring fields of Texas Bluebonnet flowers.
Here, his subject is less colorful and more prosaic, but, even though I’ve only see it in reproduction, I just love this painting. Onderdonk’s seemingly casual brush work is so delightfully brushy and textural, the usual adjective of “painterly” seems insufficient.
