I am also in the process of making some other figures; one that has been studying lines to take a screen test; one a fishmonger complete with wire basket of fish, and the last figure has just what kept Neil Young searching for.
The heart is suspended and is slightly movable...it's encrusted with what I think is pure gold pulver. My dad used to do decorative painting and after he passed, I found this small vial-like bottle of gold pulver amongst his other supplies. It was a very small vial and it might be composition leaf-powder, but it's more than sixty years old so just maybe it's the real thing.
I guess one could do an assay to determine if it is. Or maybe not.
