Georges Sand glass decanter with three small glasses

Very old liquor decanter (early 20th century) georges sand model accompanied by three liqueur cups. In blown glass, in the style of portieux or legras. Good condition: no cracks or splinters. Attention the surface of the carafe and the glasses show wear, or may be tartar. I haven't been able to remove these marks, even with special cleaners, which means you won't be able to get rid of these traces either! Take a good look at the photos, especially the last one to get an idea! Carafe cutter: 22 cm. Height of a glass: 3.5 cm.
