No, not a Chocolate Orange, this was manufactured in 1925 for Les Parfums de Marcy “L’Orange Variee” perfume. The scent comes packaged in eight individual glass sections, shaped like orange segments sitting in a painted enamel peel. The segments actually sit upside down to conceal their corks.
The scents included were: Chypre, Amber, Heliotrope, Rose, Jessamine, Mayflower, Violet.
Although novelty perfume bottles like this were popular through the 1920s, a citrus-shaped one like this was still very unusual. Because there are so many delicate parts, it is extremely rare to find a whole, undamaged example today. Apparently collectors usually have to cobble together parts from multiple sets over years of collecting to get a full example — like a beautiful orange Frankenstein's monster.
