With "only" the petals and the light and shadow and the different slabs - despite there already being three individual elements there! - something would have been missing I think --- and this something is provided by the paper hanky ... good.
Thanks for the comment. I suspect that these strange arrangements are all pieces of evidence. I never disturb them, of course. I only record them as faithfully as I can. I have no idea which trial they are evidence in, but I'm sure that it is an important one.
