This picture of 1948 was based on a pencil drawing of 1927 and was made as true to the drawing as possible. A distinctive characteristic of Lowry's work is his use of a white background and the elimination of shadows which gives his pictures a naive and dreamlike quality. He started using pure flake white as a base for his paintings in the 1920s. This was a result of an argument with his teacher Bernard D. Taylor, who thought Lowry's pictures were too dark. Lowry later discovered, to his pleasure, that the flake white turned creamy grey-white over the years.
