Victorian Easter Greeting Card with Art Nouveau Woman in Egg

What exactly is this woman's relationship with that egg she's emerging from? Bare-shouldered and chin propped on her hand with the energy of someone who absolutely knows what she's doing, she drapes herself over the shell's edge while her yellow garment slips conveniently off one shoulder. Her expression reads less 'joyful resurrection' and more 'I've been waiting for you.' Set against a dark background with a sliver of green grass at the bottom, this card somehow convinced an entire generation that the appropriate way to celebrate Christ's resurrection was to mail your relatives a picture of a woman being born, extremely slowly and sensually, from an egg. The artist was definitely aware of what they were doing. Definitely.
