"Italian Sketchbook: Harbor (page 78)" is a pencil sketch by Maurice Prendergast documenting his travel observations in Italy. The work captures a bustling harbor scene with characteristic loose, gestural linework that conveys movement and atmospheric effects typical of Prendergast's sketching practice. As a page from his Italian sketchbook, this drawing served as study material for the Post-Impressionist painter's larger finished compositions and reflects his interest in capturing light, water, and the figure-filled environments of Mediterranean coastal towns.
