Knielende man met een pikhouweel 1906 - 1945

This sketch by Reijer Stolk, at the Rijksmuseum, looks like it was made with a soft pencil, maybe even a graphite stick on thin paper. I imagine Stolk quickly making decisions, the lines searching for form, finding a kneeling figure of a man at work. I imagine the artist thinking about the working class. Perhaps it was something he pondered often as he passed people in the street. The lines are tentative but determined, capturing the weight and strain of labor. There's this ghostlike form above the figure. Was this abandoned or a change of plan? It adds a layer of mystery, like a half-formed idea lingering in the artist's mind. The conversation between artists across time is a beautiful one. Even though Stolk died in 1945, his sketches still inspire those who observe them today. I always feel like the lack of 'finish' in this kind of work invites us to complete it with our imaginations. What do you think?
