Did you bid on it ?, I left a bid on the books as I could not make the sale.
It does have a post war label.
It is a heavy piece of glass for it's size, the width of the rim is 1cm thick. I have never seen a piece of Monart glass so thick.
In image one in the previous post, the sizes A, B & C are not to scale, size B the coloured enamel layer is paper thin and give the appearance to be floating in the glass.
