Set of 3 white ceramic shelves art deco bathroom

Rare set of 3 identical shelves in white art deco ceramic. Interesting rounded fastening studs. The tablet has slight edges and cut-out angles. Very good condition, with low and rare traces of use. These shelves - formidable columned under each other - can be fixed the attachment studs down, classically, or upwards, in which case the tablet does not have a look. Rare 3 beautiful identical copies. Length at the back 56cm, length facing 47cm, heights fastening 10cm, depth 12cm. Very heavy.
