Have become fascinated by La Samaritaine, 19th-century Art Nouveau department store on the Rue de Rivoli. Currently closed, while megabillionaire Japanese owners, who recently purchased the huge complex--complete with thermal baths-- try to figure out what to do with it. This beautifully green-colored advertisement, with haughty child and lady (mother?) gently holding gloved hand of other lady, captures the antique glamor of the place.
