This graphite sketch from Maurice Prendergast's sketchbook captures a sailboat near the Granite Shore Hotel in Rockport, with the artist's characteristic notation of color values alongside the linear drawing. The work demonstrates Prendergast's practice of using sketchbook pages as preparatory studies, where he recorded compositional ideas and color information to inform later finished paintings. The delicate graphite lines and annotated color notes reveal his working method of translating observed scenes into his distinctive Post-Impressionist aesthetic.
