A dynamic composition rendered in watercolour and pencil, this work by Fernand Léger depicts a tugboat with the bold geometric simplification and mechanical precision characteristic of his Purist-inflected style. Sturdy cylindrical forms, flat planes of colour, and angular lines converge to celebrate the power and beauty of industrial machinery on the water. The interplay of pencil structure and watercolour wash brings a lightness to the subject while maintaining Léger's signature sense of monumental, machine-age vitality.
