I have never seen one of these before, I am sure they are around but wondered if someone could enlighten me. It is obviosuly meant to sit as it is in my photo but cannot think of a use it may have, other than being "what it is".
It is hand painted and hand removed to create the pattern, in the underside concave it is chromed/mirrored. It is etched "Kosta Boda" "M. Backstrom" and the number 54999 or 59999 (or similar). To the base edge it has "MB." and what looks like "DV" (see image 3). It measures, approx 6 inches tall and 7.5 inches across.
