Georges Seurat - Bathers at Asnieres, 1884, 201 x 300 cm. This work shows a group of young factory workers relaxing on the riverbank at Asnières, an industrial suburb west of Paris on the River Seine. Although he hadn’t invented his pointillist technique yet, the artist later reworked areas of this picture using dots of contrasting colour to create a vibrant, luminous effect. For example, dots of orange and blue were added to the boy's hat.
