Thank you for your interest Anne.
I will give some more details; The lower part is a hollow form.The upper part is solid. It (totally) is 33 cm. high. The diameter in the lower part is 13 cm and the solid
piece has a diameter of 10,5 cm and is 5 cm thick. It weighs 2230 grams. There is no signature or number. I bought it for 27,50 euros, because it looked so strange to me and at the same time beautiful. Greetings Nel
