Vintage French Ormolu Cake

I made this cake for my daughter's 15th birthday during a week in which we were trying to buy a house - everything was crazy and it was a miracle this didn't end up being made of styrofoam! In the end, I managed to bake a double-barreled chocolate cake, one with Nutella buttercream and the other with raspberry.  The panel in the center is made from wafer paper and is printed in edible ink with quotes from my daughter's favorite novels.
