Verceram vase in iridescent ceramic - 50s

Ceramics art verceram (montreuil). Design and emblematic colors of this manufacture in the 50s and 60s. Black exterior with iridescent reflections blue, green, gold. Pearlescent interior in cream color. Vase reference 6245-26. Height 26 cm. Top diameter 18 cm. Weight 1.5 kg. It has no chips and no cracks. On the other hand, it has traces and marks, frequent alteration of this ceramic. This is clearly seen on observation (and I tried to show it as best I could in the photos), but it remains quite discreet because the color is changing due to the many iridescent reflections. If you are interested, I give with the vase a cup of the same style (model 2610). It has more traces than the vase, and a chip in the white part. See the photos that complete the description, additional details on request.
