Spherical box in pink ceramic Willemse

Charming little glazed ceramic box of pale pink color, decorated with a sprig of lily of the valley and surmounted by a butterfly. Underneath, in hollow, we can read willemse. It was a mail order business, plants it seems to me, it is an object offered as a gift when we bought for a certain amount, it was done a lot in the 80s. So I think it dates from that time. It is in good condition, no crack, but two small defects of origin: a very small missing on the edge of the upper part but covered by the pale pink enamelling, and a small defect under the butterfly, one could have thought that it has been broken and reglued, but this is not the case because on the other side of the base of the butterfly, point of defect, it is therefore simply the trace of the "assembly" of the butterfly on the box before cooking. It measures 8 cm in diameter, 9 cm in height (at the butterfly) and weighs just over 100g.
