My favourite piece of kitchen art

This came from my parents cellar from the home I grew up in. There are 96 leaves in total. It has H.Lerche Wein on the back who I think is from about 1900. I love the simplicity of it in my 1600 kitchen cottage which is also quite contemporary. I just havn't quite worked out how to get the chocolate out in one piece - there must be a magic recipe! So probably best kept on the wall.
