Ceramic ball lamp base signed Guérin

Ceramic ball lamp base by guérin (roger or jules), belgian ceramist. Very pretty pottery work with a shiny brown bronze glaze. Production quite different from the usual guérin production but of good quality. Functional lamp and in good condition. Note a small, barely visible chip at the base and lack of manufacturing enamel in two places. Signed under the base. Height without the socket: 20cm. Diameter: 18cm.
