Gold fill, paste. Symbolizes longevity and luxury, weirdly. The horse chestnut also played an important part in the two World Wars: the British government made a call to collect as many conkers as one could, and would pay for one to turn them in. Conkers contain acetone, a necessary ingredient for a number of weapons. But it also brought a modicum of peace: the horse chestnut in the garden of Keizersgracht 188 in the centre of Amsterdam was one of the only things Anne Frank could see from the attic window in the secret annex where she hid from persecution. She describes the tree often in her diary, and it seemed to give her some comfort. Monogram "JLB", Makers mark "W & SB" with star. Art Nouveau. 1 1/4" diameter. One frame is still intact inside.
