Hi Fearn
Thank you for this explanation, now we can cross my flower question out of list. Actually, I was just shooting with questions, while not every of them will be important, thought. But, as you wrote: "someone could copy them" without any knowledge about botany (I hope I didn't get you wrong), so the question is, from where? (book, painting, graphic, nature?). I'm historian, but art historians sometimes are looking amongst the graphics for the references to their subject, like scetches, drawings etc. I know that Radu, nowliving in America, may have some problems with looking for such an answer. Maybe it's not most important. I thing the more important is knowledge about maker - and simple question why he decided to make something unusual like this.
Sorry for questioning
