I'll take it. I like Art Nouveau design. I wouldn't want it to be my only piece of jewelry, but I think it's fun (and funky), rather sprightly, not creepy. Of course, Space Queen sounds appealing to me, too and I have nothing against B movies whatsoever.
It's a piece of jewelry with a sense of humor and Margrethe looks as if she has a great sense of humor, as well as a love for poppies (they're my favorite flower, too). Poppies are symbolic for many of us, so there's that. And yeah, it would look great at Hallowe'en (especially at Disneyland).
